Hi, well this is a really funny thing. The tetris I wrote works *perfectly* well on my computer, the one I developed it on. However, when I copy the exe over to my other computer, the program runs fine, but as soon as I make a line to clear, the program just quits!

I can't explain it. Another friend of mine tried it on his computer and he says the program doesn't even let him play correctly, it just shows the pieces dropping and they disapper as soon as they reach the bottom. Is there anything that could be causing this different behavior with different computers running the same exe file?

I am using the Windows GDI and Dev-C++. Before you ask, All three of these people have Windows XP running on their computers. So it probably isn't that.

I don't understand whats up, can someone help?
