>>Try ThisForm.MyLabel.AutoSize=.t. (even if the AutoSize prop is already .t.) immediately after you change the caption. This should force the recalculation of the width right after you change the caption. I don't know why, but sometimes it is a delay between the moment when the text is changed and the moment when the width is recalculated.

Look for something else, because it's working for me even if I don't Autosize=.t. immediately after... I've tried it in class and in form and both are working just fine.

Maybe you're running an old version somehow, maybe the class is not recompiled, etc.
