I got a Mustek 800GS scanner (up to 800dpi, 256 gray-scale) to hook up to my
Gateway 486DX33V system; it came with:

	1. Scankit, a simple Windows-based program to permit you to scan
	2. Perceive OCR
	3. Micrografx Picture Publisher LE

The scanner offered me the choice of IRQ 3, 5, or 10; I picked 10.
It offered me the choice of DMA channel 1 or 3; I picked 3.
It offered me eight choices of address; I have settled on 22b.

Scankit can talk to the scanner with no problems.
Perceive can scan vertically with no problem, and can recognize characters,
but when I try to scan horizontally I get a general protection failure in
MACH32.drv at address 0001:NNNN.
From Picture Publisher, I can't activate the scanner via the 'Scan' menu-item
in the File menu, but if I hit the F3 key a few to many times rapidly, I can
sometimes activate the scanner, and then it sometimes drops out a few to many
lines from the scan.

Micrografx thinks that it is not their problem, and I'm inclined to agree.  It
feels like some sort of an interrupt problem, but why should Pic Pub be able
to get to the scanner *sometimes*?  Why should it then be able to scan
80-100%, not always 100%?  Why can't I scan horizontally in Perceive?  Does
anyone out there have any plausible theories, based on general knowledge about
scanners, interrupts, and/or interactions among peripherals on PCs?  I am
fairly experienced in some venues, but PC hardware isn't among them.

Thanks.
