But, I don't think there is anything inherently flawed with pre-spawning off threads as event handlers for the various gui elements on a window. Just build the app to not make changes to the window in those threads. In fact, I feel like that's a preferred approach to spawning off a new thread after the main thread handles window events. Pre spawning/forking/whatever shifts a lot of overhead to the application initial load time, which leads to a better user experience. Users hate waiting after clicking. All of this kind of feels like a hack to me (I know all of these problems have been solved a bajillion times before), but I don't consider myself a great GUI programmer. I picked Win32::GUI because it gave me an easy on-ramp to building a "professional" looking windows gui application. And this was the quickest, best way for me to get my code out the door... :) Thanks, Charles Alderman ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
