my computer went nuts for a while... going really slowly, 100% cpu usage even though I had nothing open. The install seems to have calmed down now and hopefully it has now taken to my system properly.
I had a problem installing it at first as i had a custom boot.ini file, so i had to revert to default for installation.
I had a few issues with MSN messenger and sp2 opening multiple copies at once and then crashing (when i only clicked it once)... but even that seems to have ironed itself out... otherwise i havent really seen any changes... i dont use IE so i wont experience that... lets just hope the problems i have had are all i will have!
