My virtual pinball with pinnballX frontend has worked as it should for several months now.
I have it set up in full screen cabinet mode with two monitors and one pinDMD.
But one day a few weeks ago I switched it on and at the beginning everything worked perfect. After about one hour the front end where turned upside down. Everything else has correct orientation: Windows, pinball tables, backscreen, DMD. Only the front-end menu is upside down.
When this happened there where several kids around and I had a keyboard connected and tucked away. Some kid might have pressed some random keys.
I have searched forums and all available settings I could find. But I have no idea how to correct the problem. Has anyone here a solution?
