On Sawtooth G4 350 Mac (OS 8.6) MS Internet Explorer 4.5 crashes hard. Tried downloading MS Mac Patch. Tried wiping preferences and re-loading. Tempory fix is to strip extensions down to minimum, re-boot, and then turn ext back on one by one (looking for conflicts). With everything back on IE starts working, and will work for 30-40 URL's. Then goes Ka-flooey again.
