I'm on a Win7 professional 64bit HP workstation, and since the 7.01 release of Premiere, the buttons in the Source and Program do not work. Can only add markers with the "sequence" "add markers" command. Play, pause fast forward etc do not work from the buttons. All hot keys work, but the buttons do not. Anyone else confirm?
Well that's not right. Can you try clearing your prefs on launch. While Premiere is loading, press Shift+Alt until the Welcome Screen appears.
When in doubt, clear your prefs. Cheers for the quick replay, all is well with button usage in Source and Program
