Re: Can v. 112 of Jumbo U2 Crash OS/2 ?

["mike shupp" mikeshupp@xxxxxxxx]

Speed may not be issue.  I had a lot of trouble with XyW 3.5
on my 1.1GHz Athlon setup -- couldn't get STARTUP.INT to run
automatically, or even to perform as it should when I entered
RUN STARTUP.INT.  Which was dismaying.  But then, to get
yet another program to run -- DOSEMU under Linux -- I was told
to disable shadowing of video card BIOS memory. And lo and
behold! XyWrite suddenly works as it should again.

Evidently, at least in earlier versions, XyWrite was making use
liitle nooks and crannies of memory in which one would not
normally expect to find a running application...

Maybe. But the OS crash comes when you open XyWrite, correct? *Only* when
you
open XyWrite -- correct? In a Desktop window, or FullScreen (console VGA)?
And
that's $M+6=16Kb *with* U2, right? (That's acceptable, certainly.) I don't
see

a finger pointing at the GRADD drivers...

One other possibility, which has affected me on two new machines.
Apparently
modern CPUs are so fast, and XyWrite loads so quickly, that the hardware
can't
keep up with the brain. I have had to deliberately SLOW DOWN my
STARTUP.INT,

with a liberal sprinkling of "BX p 1Q2 " commands -- one second pauses in
processing -- throughout. If I don't, XyWrite crashes the VDM (but not the
whole OS). It is worth a try, especially if you have a fast CPU, say 700MHz
or

faster. Does the crash come right at the start of loading XyWrite, when you
click the icon, or at some later moment in processing of STARTUP.INT? Not
enuf

info...
