    CS5 running slow only when editing certain clips


      I've searched and didn't find a situation like this one...most "running slow" questions were about the program as a whole.


      I have a project that I started a few weeks ago.  I've been opening it and editing it a few times a week.  Everything was running fine (both After Effects & PP).  A few days ago, I opened the project, and opened as usual.  However, I noticed that when I would either try to simply view a clip within the timeline/final putpur preview, or worse, try to apply an effect, it would slow to a crawl, and sometimes freeze, giving the (Not Responding) text to the title bar.  Previews from the list of source footage does not have the same issue.  It would eventually come back.


      If I try to export a finished media file, it runs much, much slower (magnitude of at least 3x times) than a couple weeks ago (the last time I did this had almost the same number of effects applied as more recent attempts, so it is not from me adding alot of new effects).


      This has been the case for several days now.


      Nothing in the project changed between the last 'good' session and the first 'bad' one...the raw files didn't move, I didn't delete preview files (and even if I did, it should have regenerated them).  The computer has been restarted several times, no difference.


      The only change that occured to the PC itself is some Windows Updates.  I did delete some preview/rendered files from other projects, but they were all in different projects' folders.


      Does this sound familiar to anyone?
