Error in window position


New Member
Hi, please see the screenshot first.
When I click on the marked "eye button" a window opens in the top left corner of my screen. Neither can I access the "close/min./fullscr." area, nor can I close it with cmd-w.

When I click again on the eye button a second window opens with some offset to the 1sr one and I can close the 2nd and subsequent windows easily.

The only way to get rid of the 1st window however is to quit MBM alltogether, which is not a satisfying solution.

I am using an iMac 27", late 2011, OSX 10.13.4, latest MBM version.

Greetings, Robert
