I have upgraded to 10.2.3. Yes it made it incrementally better. However when checking the process viewer, the CPU was being hogged by up to 98% with HP Communications. I finally trashed the software and now have my trusty Epson 740i hooked back up. I'll await the next upgrade by HP or Apple and try again. I still got error messages saying that some of the software was no up to date (scanner) and I should check the website. Pooh! > > The real solution is to update to Mac OS X 10.2.3.
