I can not figure out how those 3 above commands work.  I need to be able
to add and remove gadgets so I can position them where defined by the
user.  

With the 1 gadget defined, I tried to 
RemoveGadget(my_gadget)
(system hung)
RemoveGadget(&my_gadget)
(system request window began to appear and it hung)

I assume it must be attached to the window (my_new_window) but can't figure
out how and these commands are not documented anywhere that I can find.

I am using CManual Gadgets Example7.c as the foundation for experimentation
if you are wondering exactly what the code looks like.

thanx,
Ross
