Ack. This just happened to me today. Twice. On two different machines (one XP, one W2K), both running Premiere 6.0. What was different about today? Well, I upgraded to Quicktime Pro 6.5, and made a few Quicktime MPEG 4s. Bleh...(posted 7392 days ago)It only happens when I "Export..." It happens right after I let go of the mouse, after you pick the menu option.
Yeah, I know I should upgrade my premiere.
