System restarts

[meester]

I have build a program that connects to a mysql database.
On most computers it's working fine,
But i have some trouble:
On certain computers (win xp, service pack2, and norton AV installed) the system restarts without any explanation.
it's a normal restart, windows doesn't provide information about the restart.
The screen just turns black and the system restarts

Another strange thing: when i use the program in windows safe mode on the same computers, it doesnt happen.

Can anyone give me a quick advice.
i'm using swfkit pro 3.0 on a project i updated from 2.0)

(BTW, i tried to disable Norton, without any succes...i'm desperate)

This may be caused by some system driver. When a system driver encounters a problem, the system restart silently.

Do you have the 2.0 version of your project? Does it work well on the computer?

version 2 also restarts.
