Hello, we all know sometimes our overlay crashes and we get stuck and one spot. However, It can be fixed without restarting sk. (windows only)
1. control+alt+del or windows key, right click, and then start task manager to start up, task manager.
2. Go to processes
3. find GameOverlayUI.exe and select it
4. hit del and enter.
Steam will notice that the overlay has been closed and will reboot it.
Thats how to fix the Steam Overlay problem.
This may have been here before, but im refreshing it to make sure that steam users know.
A better way is to just not have the Steam overlay enabled for Spiral Knights. It causes more problems than it helps with, honestly.
