Using Directx 8, Visual C++ on High Spec machine with Matrox G550 Dual headed monitors.
Have enumerated each display and successfully created full screen window on each.
When the cursor moves from the primary to secondary display at their shared edge the cursor is not displayed on the secondary.
I occasionally see a momentary flash on the secondary monitor where the cursor should initally appear.
I can move the cursor back on to the primary and it works fine.
Anyone any ideas?
