Quicktime Video , workspace, V10 and 7.4 issue

[plugset]

Hello, I'm having a serius problem with Protools 7.4, when I have a Video track going out through the V10, and i try to find some audio within the Workspace and drag it to an audiotrack, I lost the possibility to see the video trough the V10 interface, the only way to see the movie trough the V10 interface again is closing and reopening the application. Is this a 7.4 bug? Digi please Help.

My set up is:
Protools 7.4
HP XW8200, 2 gig Ram.
SCSI Drives, the latest version.
Windows XP SP2 with all the updates necessaries for protools7.4
PT HD1
96
Sync
V10
Quicktime 7.3

This is happening to me as well. I'm loosing QT pic by audiosuiting a file or scrubbing. What kind of QT codec are you running?

Well I found out this happens only when I import a quicktime movie, recording directly from a beta or or something else the problem doesn't show up, so resuming, the problem is with quicktime movies and not with mxl, I think this is a kind of bug of 7.4.
I'm using the avid codecs and last version of quicktime, I've tried with the early version of quicktime too.
