I read in a thread somewhere on here, and I have been searching for 20 mins for it... The program I am looking for was described like this. It would close the application totally when you hit the X button, but would minimize it if I hit the OK button. It was said to be really small in size... Can anyone point me towards a program like this??? If it's free or pay, I don't care. Thanks for the help!!!
