Typically issues with IE 6 are skinning issues and can be solved by overriding css in the IESpecific.css file to solve problems with IE 6. Not all the included skins work well in IE 6 and I am not interested in solving it because I don't care about IE 6 anymore and think it should die and no-one should use it.
But if you still need to support it then you will have to invest the time with trial and error css fixes, it is possible to solve issues like this but it is a pain in the rear.
Best,
