I'm running DisplayFusion Pro 8.1.2 steam On Windows 8.1 with classic start menu 4.3.0. For some reason, when I click the start menu on my secondary monitor. It seems to open it on my primary monitor also. I'm 100% it was working fine when I first installed the free version. I've tried reinstalling the program and video drivers but no luck.
