Fencer: I just found that there were two "java updates" (J2SE Runtime environment 5.0 Update 6 and Update 8) installed on my PC (actually, also a notebook :) ), plus a third thing called "java 2 runtime environment SE v.1.4.2_03". I uninstalled the "Update 6" (maybe there was a conflict), but nothing happened (nothing good or bad... which appears to make the update 6 unnecessary!). Do you also have these freezes or do you just want to buy a 2GB RAM new one? Because if you don't have them, I'm sure you can give us some good advice (other than reinstalling everything ) on what we could do to have more memory or what we could check! :-)
