I have been trying to run QMODEM under Desqview for a few weeks, and
although it runs fine for a while it has a tendency to crash the system,
or cause strange things to happen.

I started to use QMODEM as a replacement for PROCOMM Plus, because I
found that under Desqview, at 9600 bps, PC Plus would lose characters.
The system I am using is an IBM PS/2 Model 60 (286).  It seems that this
character loss problem is particular to the PS/2, I think because of the
way the interrupts work.  The solution was to find a comm program which
would use the 16550 UART in the PS/2 serial channel.  Apparently, PC
Plus cannot do this (though I have heard some recent, unconfirmed
rumours that maybe there is a new version that solves this problem).
QMODEM offers this capability, and character loss dissappears.  However,
the problems are as follows:
 
	- The machine will sometimes re-boot when pressing a key other
          than Ctl-Alt-Del.

	- The font sometimes changes, to one which underlines all
	  characters which have decenders.

	- Colours sometimes change.

	- Cursor control is sometimes lost (i.e.. the arrow keys),
	  though everything else seems to work.  This happens when
	  running WordPerfect as the second program, and QMODEM in the
	  background.

	- QMODEM sometimes fails to execute at all on an open window
	  command, hanging the machine in the process.

If anyone has any comments, solutions etc, I would be pleased to hear.
I am running QMODEM 4.1, by the way, and the available memory includes an
Intel Aboveboard (LIMS 4.0).
