I posted this in someone else's iBook help thread but wasn't getting much help so I'll post it here, too. I have a 12" 1.33Ghz iBook G4 with 1.5GB of RAM and a 60GB HDD. She can easily run tonnes of apps without even hiccupping and yet I experience crazy slowdowns in Safari and Shiira. Most of the time it'll happen when I have 15+ tabs open but every now and then I experience the same problems with only two tabs open. The webbrowser I'm using will become unresponsive to clicks and keystrokes and whenever I have the cursor over it I'll just get beachballs. The rest of the system is fine, it's just Safari or Shiira that gets boggy. So.. why is this? I mean I know it takes time for tabs to load.. but shouldn't webbrowsers still be responsive when tabs are loading? I don't think this is a connection thing since I never experience this sort of thing on my PC desktop. Is it a software thing? A hardware thing? Comments and suggestions are welcome. Thanks.
