VST GUI disappear when it should not. Please help.

I am trying to get back into using Cubase now that it has ARA.

Strangely any VST that is open will disappear when the mouse pointer clicks outside the Cubase Pro Project window. The Cubase Pro Project window remains visible and when I click on it the VST’s re-appear.

I have the Xotopad midi controller on the second monitor which is multi-touch. XotoPad - The MIDI controller for Windows touch-screens . When I touch the keys to play the VST disappears. The VST does not however disappear when I play an external midi keyboard.

On another PC with Cubase 7.5 I did not have this issue.

Hi,

Right-click to the plug-in header and disable Always on Top.

That did not help.

Hi,

Is Cubase in focus or other application at that moment?

Sorry, I was not notified of a reply.

Yes the focus is Cubase and a VST is on top.
I click outside the Cubase Project window and the VST totally disappears.

In Cubase is there a repair function in the uninstall wizard?
