Try using the LOADHI.SYS supplied with QEMM for as many of the device drivers
as possible in the CONFIG.SYS.  LOADHI will place most of the device driver's
code in extended memory instead of below 640k.  Also, obviously, you should
avoid loading lots of TSR programs before running DESQview.  Also, there is
a program called BUFFERS.COM (I think) that loads DOS buffers into extended
memory.  This goes in the AUTOEXEC.BAT file.

My CONFIG.SYS looks something like this:

DEVICE=\DV\QEMM.SYS RAM ROM [other options]
DEVICE=\DV\LOADHI.SYS \DV\MSMOUSE.SYS /C1	/* Mouse Systems mouse */
BUFFERS=2					/* Set only two DOS buffers */
...						/* in regular memory */

In the AUTOEXEC.BAT:
...
BUFFERS +14					/* Adds 14 more DOS buffers */
...						/* in extended memory */

NOTE: I am doing this all from memory so you should look into the QEMM manual
for info on LOADHI and BUFFERS.

CHKDSK in DOS says I have 604k of free memory.
The largest program size reported by Memory status in DESQview is about 576k.

I have DESQview 2.22 and QEMM 4.1.

BTW, in the DESQview setup program, if I select PC Mouse for the mouse
selection (which is what I have) I get no response at all from the mouse.
If I select Microsoft Mouse, it seems to work fine.  However, before entering
DESQview, I must "enable" the mouse by running some program in DOS which uses
a mouse (like Microsoft WORD).  Any other PC Mouse users experienced this
problem or solved the setup quirk?
