It wasn't meant as a comment on your coding style, only on the fact that the control was ALWAYS being disabled and then possibly being re-enabled. I was just wondering if that was causing the effect you were seeing. Interesting that it only happens when DODEFAULT() is used, and not when the code is in the instance.
