saw this which made me think of this
http://forum.thegamecreators.com/?m=forum_view&t=152591&b=15
as you havent posted any screen shots am wondering if your project is set for fullscreen in the ide options and if the above link is what your experiencing - I had forgotten I had posted this possible bug and have just looked at it again
As I have now got 7.5 installed the same code I was using no longer showed the bug(which I never did post up in the report - dont know why!), so I have made 1 alteration as it did not appear to exist under 7.5, in order to recreate the bug - I have ensured vsync was switched off
run the following code twice, the second time remove the vsync flag or change it to 1
set display mode 1024,768,32,0
set window off
sync on
sync rate 60
make object sphere 1,1
do
sync
LOOP
now when i do same for the project resourceful posted up I get same result and if i run it in window mode it will crash the application on the first run..
bare in mind I have anti alias set to overide the application at 4x during all the tests in order for the results to show up as they have done
also bare in mind that you can control the aa setting in the same command, I havent been able to test further as Im v busy atm, when I get chance to I will revisit and post findings if its worth it in the report
edit: change line 1 to this with 4x aa in your graphics control panel(set to overide app controls)
set display mode 1024,768,32,0,0,0
this is only way while controlling multisamples that the bug is recreated, setting multisample to anything other than 0 works fine even with vsync off
