Yeah, I run the program, initialize everything. I am very careful about the order I do things in. No bitmaps are set until long after the display is set up. I set VSYNC & FULLSCREEN from a config file (I got that from one of the examples on vsync I think it was). Once the display is set early in the program it isn't changed again. I tested it with vsync set at 0 (system driver), 1 (forced on) and 2 (forced off) and the problem is still there. But only in Fullscreen mode. I don't do anything fancy with other settings (like blenders and such) as I want to be sure the program is running smoothly with normal default settings first.
It's puzzling because I wouldn't think I would be able to hear my sound sample at all until the flip was done, but it plays halfway through before the screen appears.
I have 10gigs of system memory and an nVidia GT240 video card, so I am not lacking in memory. CPU is quad core 3Ghz too.
Like I said, window mode and fullscreen window works. I like fullscreen window, but then I would have to hack away at some code to make everything display properly when I should be able to simply call a normal fullscreen mode and let the users monitor handle how to do that.
If I have to I will, but it seems like odd behavior and would be nice to find out why it is doing that.
Below is my initialization function, I cut out most of it and just commented what is there, but all code I do have was tested and works fine, I always check return values no matter how remote the chance of failing as I like to be safe...

The end of the code above is where you get the delay before the screen appears, the sound plays for about 2 or
3 seconds before the screen appears, but only in ALLEGRO_FULLSCREEN mode.
And my main function...
int main(int argc, char *argv[])
{
// set variables etc for use later here, non of these effect the intro...
initialize();
intro();
No need to show more, this is where it branches off to do the intro mentioned above.
Edit: not that it matters, but all graphic, font and sound files are loaded from a ZIP file and shut_down() you see simply destroys anything that needs destroying before the game exits.
