Sorry for not getting more information and sorry for my English, I’m from Austria, but I try. However it is going to be spooky, so be warned!
I downloaded MC from your homepage. And all the trouble begins in the moment I start the program. The pop up windows are the windows that should appear when you click one of the menu elements in the main bar on the upper left. But they are not where they should be, they are somewhere on the screen, mostly on the upper half and they are flickering around, no chance to click anything.
And now it’s going to be very strange. I made a screenshot and the only thing you can see there is my desktop!!! No MC at all. So I took a picture with my smartphone, so that you can see how it looks like.
Thanks for any help!
