There's a nasty little bug in DesqView 1.21 which prevents a program
compiled under Microsoft C 3.0 from successfully exec'ing a second
program. The problem is that the wrong segment fixups are used.
Here's a patch that seems to do the trick.

(1) copy DV.EXE to DV.TMP
(2) debug DV.TMP
(3) Enter "r" to look at the registers. Note the value for DS(=ES=SS=CS).
When we did it, the value was 20E7.
(4) Add 1000 hex to this value - in our case 30E7,
(5) Unassemble  VALUE:7652 - in our case
 u 30E7:7652
 You should see 
	MOV	DS,[BP+12]
	MOV	SI,[BP+04]
	MOV	BP,[SI+02]
	JMP	7661
	etc.
If you don't, you haven't got 1.21 (the latest version). Sorry.

(6) Type
	a VALUE:7652
	MOV AX,DS
	MOV DS,WORD PTR [BP+12]
	MOV BP,AX
	JMP 7661

(7) Hit ENTER to exit assembly mode, then write it out with w and q.
(8) Copy DV.TMP DV.EXE, then try it out.

This patch (courtesy Bill Pittore) allows us to run TELNET under DesqView
with PC-NFS. Don't call Quarterdeck about it - they already know.... :-(
