Hi Tilo, Thank you VERY much!! I really do appreciate your insight! It's very hard to find information on this topic...even within the Palm community. I've bought several Palm programming books, but very few even touch the topic of Palm animation.
I've considered using Razor for my animation, but I try my best to stay away from C++ whenever possible. :) Have you considered releasing a version of Razor in C? Obviously I hate to reinvent the wheel! Thank again for taking the time to help me! :) Robert Purcell, [EMAIL PROTECTED] BapSoft, http://www.bapsoft.com --- In [EMAIL PROTECTED], Tilo Christ <[EMAIL PROTECTED]> wrote: > Hi! > > Use 2 offscreen windows.
