What does Rhino8 break that worked in V7 6 or 5?

I made it pretty clear that this is a third party program. :slight_smile: The fact is that only Rhino 8 causes that behaviour. No other program, including Rhino 7. This means that something in Rhino 8 is wrong and leads to opening the pop-up window of Gadwin PrintScreen upon starting of Rhino 8 or at certain moments when I open and close some menu windows in Rhino 8 after the latter is already in use. This bug happens multiple times per session and is related to loading or closing of pop-up windows in Rhino 8. This bug does not exist in Rhino 7. I report it here, because the topic is regarding things that got worse in Rhino 8 compared to Rhino 7 or earlier versions.
