Hi Harry,

>yes, they are subclassed. But I can't see any relevant differences between the subclass and the vfp base. The only bits I had tweaked were the when and keypress events and I've just reset them to default to see if they were responsible. No joy.

Hmm, thats some wierd wild stuff. The only thing is try checking the Class property to make sure there arne't any more class in between this subclass and its baseclass.
