Update: This has been fixed in Citrix Receiver for Windows 4.9 LTSR CU1 and later.
Source code fix has been implemented in DesktopViewer.dll file.
Citrix is aware of this issue and will fix it in an upcoming version of Receiver.
A workaround is to save the ICA file to the disk every time prior to launching it, or to delete the ICA files from system TEMP folders before launching the app:
- C:Users<username>AppDataLocalMicrosoftWindowsINetCache (Windows8 / 10)
- C:Users<username>AppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5 (Windows7)
