Mouse may become unresponsive after you launch an App-V application

View products that this article applies to.

Symptoms

When you launch a process that was virtualized through Microsoft Application Virtualization version 4.5, version 4.6, or version 5 (App-V 4.5, App-V 4.6, App-V 5.0) on a touchscreen-enabled device, the mouse pointer may become unresponsive. When you exit either the App-V application process or the wisptis.exe process, the mouse starts to work again. This also affects RDS/terminal servers if the Desktop Experience is enabled (that is, if the default server setting is not enabled).

Cause

In some cases, App-V creates a second instance of the wisptis.exe process as part of the application launch. This may create a conflict between the wisptis.exe process that's already running (because the system is touchscreen) and the new wisptis.exe process that was triggered by the application launch. By exiting either the App-V application process or the wisptis.exe process, you remove this conflict.
