Hi ppl,my first time posting in thsi forum! well, I just started to learn to program (bought Tricks for windows game....) for windows and i have a question. how would i change this program so that if I close only one window, the whole program won't quit and it will only quit if i close both windows. Hope this comes out right... *crosses fingers*
