Re: Windows Real-time

Art,

I downloaded the updated version, but it still locks up the machine
immediately.

This morning I tried the VxD on a Windows 98 computer at work and it
seems to work fine. So it must be something screwy with the other
computer. The computer at work is a Dell PIII 866Mhz machine.

I will take a closer look at the AMD K6-2 machine tonight and see if
I can come up with why it locks up. I have SoftICE from Compuware
which will allow debugging of VxDs...

Regards,

Phil Covington
