Alright, I am out of ideas on how to fix this problem. Perhaps someone might be so kind as to take a look at the Capx and see if there is something obvious that I missed?
You can find it here: Tough to Kill Capx
The Intro Event sheet is labled as such, and that is where the handling for the Intro screen is. For the Play button, I just have it so when the mouse is over the Play button and left-mouse button is clicked, it will play a sound effect and go to the 'Play Game' layout. Pretty simple and should work. It works for me, but not for many other people.
So any help would be greatly appreciated. Thank you!
