Yea, I have not been able to open a window or do any drawing operations (eg: box 10,10,30,30) without a crash on my lowly graphics card. I could run a program that was nothing more than a repeat ... until loop, but nothing more :-(
I was testing the demo on my low spec and high spec PC. Ofcourse, it ran all the commands on the high spec PC but alas I wish to create 2D games and need them to run on any version of Windows from 98 to XP (with latest DirectX would be fine).
Thank you for releasing a demo version of DBPro, it has been useful to evaluate and try-before-you-buy. I'm sorry it is not suitable for me. Good luck in the future
