Yeah, people sometimes got this flickering thingy with dual monitor.
Have you update to Catalyst 10.7?
According to the release notes, this issue should have been resolved with this driver update.

If still having this issue with 10.7:
I'm not sure that this hotfix does the job, but do try it anyways and see if it fix your problem.

THIS IS CCC 10.7 HOTFIX CONSIDERING YOU  ALREADY UPDATE THE DRIVER.
IF HAVEN'T YET UPDATE, GO TO: http://game.amd.com/us-en/drivers_catalyst.aspx

Do report back if the problem still occurs bro..

Yup, the 10.5 is no where recommended to be used.
Ok, if you haven't encounter any issues, then just stick to the 10.4, these latest drivers are more into fixing stuff rather than performance boost.
Regardless, I'm using 10.7 now, I think is as good as the 10.4 but with additional bug fixes (e.g. VLC Player)
Prolly the cards are too superb for them to handle in the first place 
Just few improvements, but it's always recommended to update drivers to avoid any possible oncoming issues.
BTW, the 10.7 does a bit better compared to 10.6, only less than 10 minutes on the PC to update this driver, so go for it. 
VLC Player... been using that even before 8800GT was released and never encounter such problems with it. 

Don't knowwhy the ATi Team makes such a fuss over it prior to the release of Catalyst 10.7. (could have done this since Catalyst 10.1)
I got the nagging feeling that they are running out of ideas of how to push the cards for more performance, thus trying to look "busy" when working on improving the VLC Player.
