You could sure use some mouse input with the marbles. Remove the timer stuff from the DDEX3 program that we modified and add handling for WM_LBUTTONDOWN, WM_LBUTTONUP and WM_MOUSEMOVE messages in the WindowProc() function. You will need to add some code to find out if WM_LBUTTONDOWN was on the marble and then move the position of the marble relative to its last position whenever you get WM_MOUSEMOVE message.

Here is a video of it:

If you run this in debug mode you can notice considerable lag because it runs over the debugger. The video here shows the application running normally, i.e. I select the program to "Start Without Debugging" (ctrl + F5).
