kod uzun oldugundan inceleyip kapanmaya neden olan duruma bakamadim.
fakat eger bir sistem yani windows hatasi kapanmaya neden oluyorsa, bunu engellemenin yolu var elbet.

tum bu kod parcasina AA diyorum.
try
{
AA
}
catch(...)
{

}




olayini uygularsan sistem hatalari atlanacaktir ve pr. kapanmayacaktir
