In your display loop you should not call DrawPicture repeatedly. This can cause some very strange things to happen. You should change the loop to
done = false;
while (!done)
{
   done = Button();
}
This will exit the loop when you click the mouse.

Another change that you should do is to add error checking when you get the picture:

startpic = GetPicture(129);
if (!startpic)  DebugStr("\pCould not get picture 129");


When I made those changes to my project (using CW11 AND Pro) it worked fine. It scales my picture to 640 x 480 and draws it centered on the screen. If you don't want your picture scaled you should use the pictures rectangle (*startpic)->picFrame.
