I have set Greenshot to automatically copy the captured Image to the clipboard. That works pretty well in most cases. However from time to time I do not see the nasty Windows Notification that indicates Greenshot hat copied the image to the clipboard. At the same time I see strange behavior in Windows: Windows/Tasks cannot be switched anymore with the mouse, one has to use Alt+Tab/Windows+Tab for that. Windows Task Bar is unresponsive, the Start Menu does not open and the title bar of th eopen Windows are non responsive as well.
All that disappears suddenly when the nastly little window informs me that the Images was copied to the clipboard. Unfortunately, when it comes to such a strange behavior, it takes several minutes until windows returns back to normal.
Any ideas what might be the reason?
