Windowed mod in VR - 2.7

[Voolpy]

Hello everyone, when I launch DCS open beta in VR, I have a "window" mode as shown in the screenshot.
So, when I click down on the image, I act on the taskbar and not in DCS. On version 2.5, I don't have this problem. Alt+Enter does not correspond to the expected solution (even if it works by default). I have checked the full screen box, mouse limitation in "system" and VR.
 
I have to admit that I don't see how to do it. (I don't want to move the taskbar).
 
- Has anyone encountered this problem?
- What is the solution?

Same problem here. I move the taskbar to the right edge of the screen as a workaround when I play DCS.
