What "search function"?
What exact version of After Effects?
When you search in the project window for items by typing in a name.. it will hang on the first letter. And it is AECS5 as mentioned in the original post and it is 100% up to date.
Often people think their AE is up to date when it isn't (CS5 especially would say it didn't need to be updated when an update was actually released for it), that's why Todd asked for the exact version number even though you said CS5 in your original post.
Has the search function ever worked for you or has it always hung like this after an hour's work? When did you first notice the problem?
It was up to date because I'd noticed a probelm with Premiere audio from my Convergent Design recorder that required me to update the whole CS a couple of weeks ago.. (the audio was being offset on the left and right tracks - go figure, it was a known bug). Re your question - no it started happening 6 months or so ago. They are big projects that I work on but I couldn,t seeanything going on in the resource monitor that would indicate large processor use or a particular app going crazy. It might have been the Wacom driver but it was doing it without the Wacom attached and with it.
Anyway too many bugs in CS5 so I bit the bullet and upgraded to CC so no more problem.. pretty impressed so far.
Now if only Adobe could solve all those multi-proc bugs (muddled fields, corrupt frames etc) then this thing would fly.
Thanks for trying to help but I needed to get projects out the door and this was just one more roadblock.
I'm glad you've gone to CC. It's got some great new features! The update coming in a couple of weeks will add even more to it.
