Handles are Windows tools to manage limitted OS resources like bitmaps, brushes, Fonts, etc... It does happes that Handles are a limmited pool also and when you load many apps on your pc and one of them either have memory leaks of mis handle the handles 😀 you can run out of them. If this was on your local workstation a good old reboot will take you back to normal operating conditions. If you are a hard die guy and really want to know whos the responsible program in Task Manager and Display "Handle Count" 😉

Cheers,
