Since getting the latest Safari Update, it's started locking up my G5 (total lock, the only way out is to reset using the power button on the front of the tower) with increasing reguality. does it lots (attempting) to access lots of the threads in the Lounge on this very forum.
I would switch (to Firefox or Camino), but Safari is the only (decent) OSX browser that propprely utilises the OS's built-in spellchecking. And as I tend to post in quite a few forums, and my spelling/typing is appaling, a working spellchecker is really important.
