Known incompatibilities
1466 Crash on startup in certain versions of Windows XP e.g. Chinese The application cannot be used with certain versions of Windows XP. Contact ClearCanvas Technical Support.
792 Images don't display on grayscale monitors The application does not support dynamic/static grayscale palettes on older Dome/Planar monitors/video cards. Images may appear blank or there may be rendering artifacts.  Thoroughly evaluate image quality with your display configuration to ensure that it is supported before deploying for clinical use.  Otherwise, newer display device(s) may be required.
2920 Some controls appear black on some, usually older, Dome monitors The application does not support all Dome monitors, particularly older models.  Thoroughly evaluate image quality with your display configuration to ensure that it is supported before deploying for clinical use.  Otherwise, newer display device(s) may be required.
     
Configuration warnings
7796 Key Images should not publish to default servers by default The current default is to automatically publish to default servers, which may not be correct for every site.  It should be updated to suit via Tools/Options/Key Images.
8121 Exception generated on running workstation from network The workstation should be installed only on the local machine.
8449 DICOM related settings are not migrated on upgrade Some settings are not being migrated as of yet on upgrade.  These settings include those in the sections ClearCanvas.Dicom.Network.NetworkSettings, ClearCanvas.Dicom.ServiceModel.Streaming.StreamingSettings, and ClearCanvas.Dicom.DicomSettings.
     
Known defects
6696 DICOM Editor save button appears to not save modified values As described in the User Guide, upon editing a value using the DICOM Editor, click away from the edited tag before saving.
8033 Edits made in DICOM Editor are not seen in viewer if study was previously viewed in Study Filters Due to a caching issue, changes made in the DICOM Editor may not be visible until the user restarts the Workstation.
4079 Viewer process is limited to 2GB of process memory even when /3GB switch is set No workaround, but the Workstation has a memory management feature, so support for 3GB process memory is unlikely to be required in practice.
4999 When there are multiple default servers and one fails to respond in time, no priors are displayed in RCCM Most often caused by server downtime.  In Tools/Options/Default Servers, un-check the offending default server until it comes back online.
6682 Viewer cannot render monochrome images with "rogue" palette color LUT tags The viewer cannot render monochrome images that have Palette Color LUT DICOM attributes present but empty. The workaround is to edit these images and remove the Palette Color LUT DICOM tags.
8394 Key Image display sets with multiple study references always show a placeholder image for images from the "other" study When you capture key images from more than one study in a session, all captured key images are added to a new KO series in all of the affected studies. It is arguable whether or not this is the correct way to do it, but the reason for doing it was to alert the user that key images were created in the same session for multiple studies regardless of which study was (later) opened.

However, when you open one or all of the affected studies (even via multi-selection), only key images from the study to which the key image display set belongs are shown; others are placeholder images.
5750 MPR fails to render 8 bit volumes No workaround, but such data sets are very rare.
7910 MPR and Fusion do not account for varied Modality LUTs in source images MPR data sets will appear to have a "banding" effect.  No workaround.
7862 Does not render overlays from compressed images if overlay is embedded in pixel data  Images like this are not DICOM compliant.  Configure the modality to use the overlay repeating groups instead of embedding overlays in pixel data.
6785 Opening study after display configuration change shows black workspace If this problem occurs after changing monitor configuration, restart the application.
8133 Reference lines are not captured in clipboard images No workaround.
7818 System.OutOfMemoryException thrown when workstation attempts to send really large images Usually very large uncompressed multi-frames on the order of hundreds of megabytes.  Possible solutions:
 - Close all unnecessary applications.
 - Consider configuring the modality to produce single frame, or smaller multi-frame images.
 - Configure the modality to create compressed multi-frames; the problem will not occur.
 - Consider switching to 64 bit workstations.
 - Consider using a USB flash drive to move the files manually.
8266 Large multi-frame images cannot be written to media Usually very large multi-frames on the order of hundreds of megabytes.  Possible solutions:
 - Close all unnecessary applications.
 - Consider configuring the modality to produce single frame, or smaller multi-frame images.
 - Consider switching to 64 bit workstations.
 - Consider using a USB flash drive to move the files manually.
 - NOTE: configuring the modality to create compressed multi-frames will not fix this problem.
3914 Deleting log file while application is running causes strange behaviour Only workaround is to stop the Workstation Shred Host Service, close the Workstation application, delete the log, then restart the service.
8226 Media writer provides no progress during "Creating disc image" stage, which can take a very long time This stage may take a long time, depending on the size of the images being written. Wait.
8819 Viewer will not print/export Fusion images  There is an issue with exporting and printing Fusion images - these operations may or may not complete successfully.
To workaround, toggle the colour bar overlay off before attempting to print or export. Alternatively, consider taking a screen capture.
