Symptom

In a Citrix environment, when the main window containing multiple DataWindows is opened and the user begins browsing through the rows, the application freezes, and CPU usage spikes. If the user minimizes the application via the Windows taskbar and then restores it, the application resumes normal function temporarily, but the issue reoccurs after some time.

Environment

Citrix
PowerBuilder 2017 or Later

Cause

MS Touch Keyboard service/process seems to cause that problem.

Resolution

Disabling the MS Touch Keyboard service/process
