Mac OS X 10.2.2
iMac DV slot loading G3@400 512 MB RAM

I was used to run LW since the earlier OS X betas.
I upgraded from 2.7.9 to 2.7.13 and had a very bad surprise

While 2.7.9. opened and ran acceptably fast, 2.7.13 takes about 4 minutes to open, sticking long on "Loading User Interface..." splash screem. After LW eventually opens, it is very very slow e.g. in computing the numebr of shared files - while in the past it was pretty fast to do that.

In addition, it slows down a lot all remaining open applications. Using top, I see an average use of 27% CPU (!!!) and 18% for Window Manager (!!) during the sticky opening screen.

I last updated java together with the OS update.
I think that this is an unacceptable performance drop - 2.7.9 ran smoothly and fast below OS X 10.2.1. Is there any problem with the new 10.2.2 or am I missing something?

Ciao
