Subject: more interrupt info

OK, some more info that might shed some light on my problem.

I wrote a simpler program that generated an slow interrupt rate and printed
out a character to the screen using putchar().  Pretty standard interrupt 
debugging method (for me anyway).

I page faults about 4 in 5 times, else it runs ok.  I keep running the program
from the DOS prompt, straight after it exits I try and re-run it.
It seems that if the machine is in real mode when trying to setup the interrupt
tables (or whatever the Protected Mode structures are) it pagefaults.

I have never had these problems before.  Why would this suddenly start occuring.
I am using a 386/4Mb machine, but it also happens on my DX4/100 with 16Mb.
Using V2beta2

Strange how it runs sometimes, but most of the time it doesn't.

PS.  Which is more stable, V2 beta2, beta3 or beta 4 ????
