"locking existing frames" when RAM previewing in AE8

anyone else getting stuck when RAM previewing? I'm working in a really large project (but this never happened with the same project in AE7) and when I RAM preview the info box sits at "locking existing frames" for a long time (like about 10 minutes) .. then I'll click in and out of AE a few time and it will start to RAM preview ...... I'm only trying to preview about 2 seconds.

From Adobe Forums:
"Yeah, these issues have been known to happen. CS3 will play sound differently from AE7 and sometimes it frowns if it finds different settings stored in the project files. If the settings aren't already correct, you might be able to prevent the issues by setting your audio sample rates, number of channels and output mapping to the exact same settings as they were on your old system. Also turn off any of those rubbish perceptual audio "enhancement" functions. If that doesn't bring any improvement, then as they say in software developer circles: removing the audio, re-importing it and placing it on the timeline is an acceptable workaround."

If the audio is normal, garden-variety stereo or mono AIFF or WAV (accept nothing else!), but you're trying to RAM preview in a really long AE comp, it really helps to truncate the Work Area.
Go to the point where you want the preview to start and hit b for Begin, then go to the point where you want the preview to stop and hit n for eNd. AE will now only think about previewing that portion of the comp -- it won't try to render the audio for the entire comp.
For more information, search AE Help for RAM Preview and Work Area.

this really sucks
firstly my preview area is only 5 secs, secondly my project is such a zoo (I'm blaming the editor...) that I have no control over what audio formats I've got dropped on my timeline, I just need the dang audio to preview in a timely manner without locking the existing frames forever.
when it it finally runs the preview it renders like lightning after thinking about it for forever. it's almost as frustrating as the 'initialising background processes' for multiprocessing that's just made me turn MP off on my Quad core...
Can somebody at Adobe please just make the simple things work? I'll take that over any new features they're dreaming up.
Let's be clear, faster previews please, make the audio work please, and more stability thanks.
