BSOD when starting IceExt on one of my machine.

I've install IceExt on three machines. two of them worked fine. but on this one, BSOD occured when starting.

All of the machines is:

OS: Windows Server 2003 3790
DS: DS3.0 Build 1268
Software installed: VS6 & VS2003 both.

Machine A is IBM ThinkPad i1200 Notebook with a PIII500 CPU.
Machine B is a desktop PC with I815EP chipset & PIII933 CPU.
Machine C is a desktop PC with VT693 chipset & PIII733 CPU.

IceExt works fine on Machine A&B. BSOD on Machine C.

When BSOD occured, the screen of S-ICE look like this:

EAX=C0201C00 EBX=00000000 ECX=FAFBBBA0 EDX=804EB28A

Display Window:

Break due to KeBugCheckEx(unhandled kernal mode exception)

I've rebuilt the IceExt.sys with 3790 DDK. Problem exists still.
Version 0.50,0.4x has this problem on Machine C all.

Maybe it's something wrong on my machine.
I give you this message is ONLY inform you.

Thanks for your software.
Best regards.
