A JAWS user who is using a published application encounters a problem with black display in CITRIX.
To fix this problem please add the following parameter to the jfw.exe shortcut:
-DisableOverlay such as the example below:
C:\Program Files\Freedom Scientific\JAWS\2022\jfw.exe -DisableOverlay
If using a CITRIX Published App, this should be done on the path to run the published JAWS on the CITRIX server.
