Curser disappears

Following yesterdays update, if I click on any apps the curser disappears.
Click alt cmd brings back the curser, but it keeps disappearing.

 

Hi RogerC4, please reinstall Parallels Tools and let us know how it goes.

 

I've tried that but the same thing happens.

 

I reinstalled tools after the update. How do I uninstall tools to try again.

 

In order to uninstall Parallels Tools use this link.
