Not really, but a good thought. The issue is that before a programmatic change to left, top, height or width, I need to save the Anchor setting and set it to 0, and then afterwards, I need to reset it to the original value. I was hoping to encapsulate all that code within the base classes, but with no way to distinguish programmatic change of size from interactive, I'm simply going to have to do that every time size is changed programmatically.
