It took me a long time to figure this out. I have finally tracked this problem down to BoincTasks thanks to Window Focus Logger.

BoincTasks is often taking focus from the active window when its minimized to the tray. Sometimes the computer is almost impossible to use if I'm trying to type something, like this post. I've tried to disable notices and warnings, but haven't got a solution yet. Is anyone else having this problem? I'm on 1.80. Actually I'd like to go back to the old version I had before installing this one, I don't remember the version number but it didn't do this when using it a few years.

After this my gpu jobs only show in the gadget. I restart and restart process made BT program crash. I had to clear crash message so computer would reboot. After computer restarted this gpu job condition stayed. Checking today I find if I uncheck Show GPU Task setting the jobs show. The setting function seems to get reversed from normal!
They always show in the gadget either way.
GPUGrid and Poem run on 650ti but I don't know which at time of crash!
