This is driving me mental.
When working and editing on larger sessions - especially 5.1 - The Trim tool is operating incorrectly:
So while in trim mode, and ie clicking and holding to adjust a clip boundary, if I 'let go' and move my mouse cursor to continue on with another task, the clip will NOT stay where I had 'let go' and instead moves with my mouse cursor! It's more apparent the more Protools has to think about, so if I'm ie: trimming a group of 40 tracks, there's that much more time for it to adjust wrong after de-clicking while it's figuring things out.
