Comments

Please note that if you set fUpdatePos to FALSE and change pt during an LTANNEVENT_MOUSEMOVE, you must update the cursor each time a change in pt occurs during LTANNEVENT_MOUSEMOVE. You must also update the cursor at the LTANNEVENT_LBUTTONUP message.

The MK_XXXX values are defined in the Window header files (WINDOWS.H for 16-bit MSVC compilers or WINUSER.H for 32-bit MSVC compilers).
