Brain Teaser: Work in fire fox, safari, but not in IE ?

[eatfishy]

I've created a chat room website and the alignment is off. The CSS and HTML coding appears fine to me. Does anyone know why it's misaligned?

 

1) Please goto www.simpoware.com/simpochat

2) Login as guest

3) You'll notice the misalignment in the lobby area.

4) Also, IE doesn't like overflow I guess? When using overlow in a <li>, the data is shown on the next line instead. The chatroom name is not in line with the user count. No idea why on IE, but works fine on firefox and safari.

 

Please help me...
