--- Comment #6 from David dav75uk@yahoo.co.uk --- Yes confirmed. If I move the external monitor to the left of the laptop monitor, close and restart, I now get a problem where the window size is again mostly on the laptop, but the window is very narrow. So it's most likely a problem that it's incorrectly positioning it and not able to calculate the size properly straddling the screen.
