Have you ever witnessed this scenario - you create some textboxes with mtext then need to change the height of the text? No fun! When you resize the mtext, the textbox doesn't shrink with it. . . i thought I was forever doomed in the doldrums of despondent textbox resizing, until <dahdahdahDAAAAH> I realized you can set the width to 0 and the textbox will resize itself according to the text size! I suppose you all knew that, but I was too excited not to post.
