[2022] The buttons are not working properly

estrid said: Problem solved. I had the same problem on live server and when working on a service request there I noticed this strange phenomenom: There is faint grey square where the non-working buttons are. Even more strange it was when I had taken this pic and sent it to SD, it disappeared and the buttons were working again.

Seems like a windows issue to me. I had similar problems in the past, when a program did not close correctly. After finding it in the task manager and closing it, it was resolved.
But this is not a game issue. ^^
