No problem
I only never tested the coords with other resolutions then 1024*768. So you might have to change that.
[EDIT]
Seems i might forgot something to mention...
You should call the display() function each frame.
Like I do have in StartFrame:
Code:
cout.Display();
lcout.Display();
rcout.Display();
mcout.Display();
(*other_gFunctionTable.pfnStartFrame)();
