I've read that there are lots of things changing in 10.4.3; among  
them something having to do with Spotlight. I assume that it will  
take some time to debug it if there really are big changes coming. I  
assume there will also be changes with PDFKit also.

By the way, I was having some problems with long pauses, with the  
beach ball, when going to the Extensions Tab in RCDefaultApps and the  
problem ended being related to LaunchServices Cache. This problem  
also shows up by displaying the same application multiple times in  
the Open With Contextual Menu. The author of RCDefaultApps (and also  
ManOpen) told me about this fix:


which deletes and rebuilds the LauchServices Cache. This corrected  
both problems and also stopped mdimport from taking 17-20% of CPU  
folr a short period of time every 10 seconds. There is a downside to  
this: this also will reset the "application-has-been-launched-before"  
flags, so you will be prompted the first time you open an application  
by double clicking a document. That extra click one time per  
application was definitely worth it for me. Did it solve all of my  
problems? No, but it has further reduced the times I run into them.

Good Luck,

Herb Schulz
