I'm using the lastest version from Adobe site..
i'm using windows 8.1, and i read the help file. before this version, i used pro 5.5 and this problem never occured.
I've tried to edit several diffrent files, and the overwrite/insert buttons are just not clickable, it's like the timeline is locked or something.
I have no idea what is the reason for this
This problem started from the second i launched Premier Pro 6.
