>I've downloaded and tried to implement Chris Chinnery's form resizer as written up in FoxTalk. It works beautifully, but I haven't figured out what to do about controls added at runtime. Has anyone worked with this?

Any resizer class has to keep some information about initial size of the objects as they were before resizing. Open the resizer class and look for any method named RegisterObjects, or any method where it checks the .baseclass of the passed parameter (the surest way to find a recursive method). Look at what it does, and then find a way to pass your new objects as parameters. Keep in mind that it may expect the form to be in its not-resized state while you're doing that, because most of the resizers base their calculations on this initial state.
