Allan, I'm going to have a go at this pop-up in the old development branch. I'm attacking this one because it appears to be as complicated as a Signal0 form can get ;) That is, not only does it display information and hide when the Ok button is pressed, but it also returns info to the rest of the program. Get the tree of classes right for this one and the rest'll be easy! So, I'll port it over to the rae branch as is, and then I'll start delving. Expect LOTS of questions! Have fun, Angus
