Hello Mark Sibly
I switched to a new computer (see specs below) and noticed that only 2 or 3 of all Fullscreen Blitz3D Programs I have written or have downloaded as Demos do not run proper anymore.
If I change in settings of GeForce 7800 from automatic detection to SingleGPU then the programs seem to work normal.
When I compile them as Windowed they run normal as well.
It is hard to explain but I try to describe what I see:
Cameras get mixed completely wrong, if you have a normal 3D-Szene and have a SingleSurface System for displaying Text and HUD etc... Vertical Mouse Position changes Graphic Card 1 Memory to Graphic Card 2 Memory and shows its contents linewise...
CameraZoom does make the picture on Screen bigger or smaller but does not zoom depending in which Card Buffer it is displayed.
Flip True or False are not changing the following action:
Starting a fullscreen program it starts displaying the upper half rendered and lower half black and reveals part of the rest at a speed of about 5 lines per second. Showing a graphic (for instance a mousepointer) and moving the mouse you can make the picture complete while moving the mouse to the bottom of the screen.
But still the lower 100 lines are only changed when there is the mousepointer and Flip does not work for the lower 100 lines at all... there is only one graphic or object rendered over the other leaving the former contents as it is...
