I've fixed the right column margin problem in IE6. The updated version is now in the
sandbox. I will include the fix in the next SP (within a week). If you need to test it on your machine now contact me at daypilot @ annpoint.com and I will send you the current snapshot.
The rendering is still not perfect in IE6 (the right event border is not visible when there are too many concurrent events in a narrow column). I'm playing with it but the behavior of IE6 is really weird (FF2/IE7 works fine).
