ProTools 9.0.3 Loop-Playback Selection issue

[hpfmn]

Hey Folks,
since I updated ProTools every time I'm in Loop-Playback-Mode all selection latches (I mean every selection you do gets summed up with the selection you did before - track wise and selection wise)

Thats pretty annoying. Is that bug or a feature (and I have to disable a preference?)

If I'm not in LoopPlayback it just play a few seconds and then stops.

Could Somebody tell me how to downgrade to 9.0.2?

Okay what worked was installing the 9.0.2 Update again - now everything works again... so lesson learnt don't update ProTools if it's running and you need it for work

Here is a Video demonstration the selection issue:

The Playback issue is that in not LoopPlayback it starts to play just a second or so and than stops playing if you hit space.
