Teamviewer session will not minimize

[teecee]

Hi all...
I've recently upgraded to a new version of Teamviewer for Linux,   11.0.57095 , wine 1.6

The problem I'm experiencing is when I've a session running against another of my systems & want to minimize the window, it won't stay minimized....it does try...the window minimizes
down to the bottom of the screen as per normal but immediately re-maximizes....

Any assistance would be greatly appreciated,

Cheers,
TC
