    preview difficulty


      In my first CS5 session, previews were jerky -- seemed to degrade and then sharpen every 2-3 seconds, a sort of pulsing. I'm using the same files and environment as CS4, where the problem did not occur. Tried different project settings, same result. Editing and exporting went fine (the performance improvement on export was noticeable). Pre-rendering the files reduced but did not completely eliminate the problem (and CS4 previewed the same files without pre-rendering). Am I missing some simple setting? Could there be a conflict with Quadro FX 1800 in CS5 that is not in CS4? Thanks in advance!
