CS6 timeline not redrawing properly

Question

I just installed the Premiere CS6 demo on my Mac Pro (Lion 10.7.3), and I've been playing with it for a couple days. So far it's worked like a dream, except for one really strange glitch: in one of my sequences, the timeline doesn't want to redraw when changes are made. When I switch to this sequence, I either see the previous sequence I was working on, or this:
When I mute tracks, perform edits, apply effects, etc., the changes occur but do not appear in the timeline. The only way to get the timeline to redraw is to scale the window or change the zoom level.
The really strange thing is that this only happens in one sequence (that I'm aware of), while all the other sequences seem to be unaffected. I've tried duplicating the affected sequence, but the same problem occurs in the duplicate.
Any ideas how I can fix this?

@Chris: First, I should mention that CS6 has come with some massive stability improvements, and I would go so far as to speculate that it's now less crash-prone than FCP7. I've been cutting a native AVCHD feature in Premiere—I started cutting in CS5.5 in February, and I made the bold decision to change horses in mid-stream and finish the edit in CS6 because the gains in stability and functionality were so substantial.
The most serious issue I have experienced involved syncing multi-mono audio files into merge clips and forced me to re-sync all my dailies, but word on the street is that CS6 has fixed this bug.
I guess my biggest problems still extant in CS6 aren't bugs so much as lacks of functionality. For instance: if your media goes offline and the files don't have unique names (as is the case with AVCHD files, which are named sequentially from 0 on every card), it can be very difficult to reconnect the footage because Premiere only prompts you for a filename and doesn't provide any other information (shot name, enclosing directory, etc.). Another inexplicable problem: searching and editing metadata in the browser takes FOREVER on my system (as in: enter the search term, go get a cup of coffee, come back and see if the search has finished). Not sure if this is because I have so much footage in my bin or if it has to do with native AVCHD cutting or what.
I've been nonplussed with Premiere's inability to take only the used footage in a project and transcode those files to a different format with handles, something that FCP has done perfectly well since 4.5 or earlier. (There may now be a workaround to this problem if you're trying to render out DPX sequences by using "Send to SpeedGrade" — haven't really explored that yet.)
Adobe's priorities can be a little odd sometimes (case in point: what use is Prelude if it can't sync double-system sound? I haven't even opened it because it seems so totally pointless) and I will admit that I've briefly entertained the notion of switching to Avid (or …Smoke, or something?), but on the whole I've been quite pleased with Premiere, particularly with the improvements made in CS6. The real strength of Premiere (and what ultimately lured me away from FCP7) is its transcode-free editing, which handles AVCHD beautifully. I haven't tried cutting Redcode footage in Premiere, but I hear tell that the workflow is pretty slick.
