Trigger Bug

[qwerty]

Hey guys,
I guess I need your help. I want to create some breakable windows. Actually I already made them. I made 6 windows with damage trigger. But on 5 windows my experience the following http://www.xfire.com/video/5e08bc and 1 is working perfectly with the same script. Almost every time other brush is breakable and unbreakable in the same window. I checked triggers, brushes but everything is good.

What should I do?

My script btw(but it's good):

torles(trig,br)
{
	trigger=getent(trig,"targetname");
	brush=getent(br,"targetname");
	for(;;)
	{
		trigger waittill ("trigger");
		brush Delete();
		break;
		wait 0.05;
	}
	iprintln("kitört");
}
