IE 5.x is ancient history now. If you are still using any IE5.x, even on a Mac, it's time to upgrade. Upgrade to IE7:

Today we released Internet Explorer 7 for Windows XP. I encourage everyone to download the final version from http://www.microsoft.com/ie.

[ IEBlog : Internet Explorer 7 for Windows XP Available Now ]

Of course if you aren't on XP yet, then you should be upgrading your OS as well. What have you been waiting for. If you are on a Mac and still using IE, time to get a real browser (unless you are on OS9, then time to toss your Mac and buy a new one). Don't like IE? Cross grade then, but please stop using IE5.x. Prefer IE6? You're crazy.

If, like me, you make the websites for a living, it is time to stop ignoring IE7. People will start using it. If your autosense code doesn't account for IE 7 (like the CVS website didn't until a few weeks ago), please update it. If your CSS layout is all wacked out on IE 7, well they aren't going to change it anymore, just learn the new tweaks, and forget what IE5.x needed and lets all move along.
