This just started happening after I customized the toolbar. I used the self install zip version, installed it on my laptop, then copied that folder to my tower PC. At the time I didn't know the program uses that damn Doc. & Set. folder for three additional files including the .ini file. Those were re-created after I ran the transfered program on the tower PC.
I delete all three of those files and let the program re-create them again, but the problem remained. I have noticed the audio continues to play as does the time line, but the video freezes/ I can stop the playback, but can't resume it again, nor close the program. All the menu functions do respond.
I never saw this behavior with any program before. A video screen lockup & the inability not to close the program before.
