Comments:

This function returns an absolute screen position.

Position the cursor with MOUSE AT , ; where x and y are local coordinates of VFP main window. After that read the cursor position with GetCursorPos function. That gives you a difference between local and global coordinates.

Put = INKEY(0.1) or any other delay between setting and reading the cursor position. It seems that without such delay VFP does not have enough time to inform the OS about mouse cursor repositioning.
