Kontakt window open in Cubase 6

Hi folks, back again…it’s not fine it’s still going on :confused: Also, not just Kontakt. Any vst I have open disappears after approx 30secs, along with the transport bar. The main window stays open fine. I have to click the mouse on the window to get the VST and transport bar to reappear.

It is extremely frustrating and no doubt I am missing something basic but can anyone help?

Thanks :frowning:
