I created this php page just to show that IE is a really bad browser whatever M$ says.
It's just the implementation of something I read about on usenet.
Don't ask me how to improve IE's security setting, I consider IE beyond saving and have already switched to a different browser: Mozilla.
By now even microsoft should have fixed this problem, I haven't checked though (no windows install at hand atm).

If you can see a frame with the contents of your harddisk above you're using IE and you should tighten up on security.
