Q Light Controller+

When I recently maximized my QLC+ screen, the normal windows frame including the minimize and multiple windows controls in the upper right corner. I have no idea what I might have done to cause this, and a cursory search of the web doesn't give an answer. This has happened only with QLC+ and started just yesterday. It's distressing that I am unable to "de-maximize" this one window.

Any ideas? PLEASE??

Did you try F11 and every combination with Ctrl, Alt and Shift?
