Wow, Steve ... that is a weird one! It doesn't seem to happen on other controls (I tried it with a ListView and a Grid), so it's definitely a bug! I tried several different things to try and get around it and just couldn't find a way to do it. I'm going to try and post it on another forum I participate in (GotDotNet) and see if anyone has any suggestions.
