I have an Lenovo Z50 laptop(Win 8.1), and a 21" monitor hooked up via VGA. They are running the same resolution (1920x1080)

When i open solidworks on the second monitor, a smaller window pops up every time i turn the model, and if I just click on it, it will stay there until i move the model again.

It looks like this:

Changing the resolution doesnt solve the problem either. If i dupliccate the desktop indsted, the problem disappears.

What could be the source for this?

Best regards
