Mathias,
It's something else, look at the pic, the cursor is on the two dots .. in the top in the left panel. If i now do Edit New File, nothing happens.
After i restart Mc and do the same, i get the dialog.
I suspect it has to do with Sleep / S3, could that be?
I seldom reboot this pc, just wake it up in the morning. I even made an Ahk keycombo to restart Mc quickly.
