I have a problem where the VBoxManager program stops recognizing mouse clicks / highlighting controls when they are moused over. (This also happens to the guest machine at the same time.) This happens with a few mouse clicks of the VirtualBox manager being opened / guest being used. The input focus stays on the control it was on, but buttons are impossible to click etc.
I've tried
- uninstalling / reinstalling the current version of VirtualBox.
- Installing an older version of VirtualBox
- Disabling startup programs
- Switching to a different user account on the same machine -didn't help.
No other program is having this problem. (I first encountered the problem shortly after the last Microsoft Patch Tuesday, but I don't think that's relevant).
I figure this machine has a setting or file that screws up the underlying GUI toolikit so that it doesn't handle the mouse correclty- but I don't know where to look for it. Can someone familiar with the host GUI suggest something I can try? It's rendered my VirtualBox install almost completely unusable.
