    MessageBox problem

    I built a win32 application. In the program I use MessageBox on several locations. For some reason some messege boxes cause crashes to the program. I even tried checking the returned value, but the program doesn't reach this stage.
    I tried switching to MessageBoxA, still no good.

    Any ideas?

    BTW, they all use the same window handle and are foramtted correctly.

    Outside of your DOS world, your header file is meaningless.
