GET sloppy!?!? The ONE application that I can count on to lock my system up "tighter than a bull's ass in fly season" is good old Internet Explorer. This didn't start until Microsoft's "strategic decision" to "merge" the browser with the operating system.
I am test-driving Opera, but I can't rate it on a par with IE as far as usability goes--clunky is being kind.
I've used Windows since pre-version 1.0 (i.e. actually ran the runtime version that shipped with Micrografx "In-a-Vision"), but DAMN, Linux is looking better all the time.
That is completely at odds with my experience. I switched from Netscape to IE at version 3.0 of each because Netscape was crashing three or four times during a two-hour session of browsing. In the four or five years since then, I'd guess IE has locked up perhaps three times total, and I don't recall any lockup in IE6 on Windows XP, which is what I've been using for the last nine months.
