I suspect this may have something to do with your values of x and y which look like they may be negative. As I said earlier using values of x=0, y=0, cx=SM_CXSCREEN, cy=SM_CYSCREEN the window will fill the monitor. The values you are using are different from this, thus your results are different. It's time for a new signature.

I remember in school we had fun with a teacher. We wrote a little calculator program that would disable all key and mouse input and show a BSOD image if you did a calculation that returned a number greater than 100. Then posed the question to the teacher: "why did my pc just crash? it's just a small calculator app." So the teacher comes over, sees the BSOD, tries a few keystrokes, does a hard reset. After reboot, we run the app again and the fun starts over. We kept the teacher busy for the better part of the class while she figured out what was wrong with the pc. ;P

It is better than what my High School teacher wanted to switch over to. He wish the AP course would do VB instead of Java. Personally I preffer C++ to either one.
