I think this may be because of windows 10 since I never had this problem in win7. Have it set for windows xp SP 2 compatibility mode. When closing UOAM it will crash on exit but the .exe will not actually close. It kinda of just becomes unresponsive and needs to be killed via task mgr. You CAN close it with the discard settings and exit option. But then I can't ever customize anything. Anyone else run into this issue?
