I am running macOS Catalina 10.15 Beta in a virtual machine on Parallels Desktop for Mac version 15.0.0.
I installed the Beta on top of Mojave what was working well within the VM. Unfortunately, after installing Catalina Beta, I cannot drag any windows.
When I click on the title bar of a window and drag, the window moves a few pixels and stops. If I repeat, I can barely make progress, progressively moving the window a few pixels at a time. Obviously inching along a few pixels at a time is unworkable and renders Catalina Beta useless.
This problem affects windows in all apps: the Finder, the "About this Mac" window, the Feedback Assistant window, and so on.
Any workarounds or fixes?
