I have strange thing going on
On link you can see a problem page - in IE strange thing is going on:
boxes/simple.tplMembers Login should on the right but in IE is under - guess because the float: left is ignored here.
When both columns are fixed width ( i.e. 600px and 200px ) it's ok, but when width is floating ( here 75% and 25% ) IE ignores float - the same happened with footer but I used fixed width
Any idea how to make right column to be shown on the right not under??

Thanks in advance

Problem almost solved...

IE isn't ignoring the float at all.. but IE6 is FULL of nasty bugs many of which pop up with floats.

Looks ok, did you figure it out ?

Yes - I found solution on alistapart.com - not really the solution but replacement - just made right column fixed width and whole floating and had to make different css for ie of course but it works

You can see slight difference between width of right column but it doesn't matter
