I'm not sure what causes this or why. All versions of Microsoft
ScanDisk (from MS-DOS 6.0 up to Win98SE even) seem to have trouble
with the arrow keys while in QEMU. Some versions can't work it at all
(Win95), while others randomly go to buttons (Win98), while yet others
go back to the first button almost immediately (MS-DOS 6.x).

This might be because some INT 10h/16h code fails to save registers
correctly in the bios. I'm telling you this because your problem
sounds similar to what I experienced when I fixed the win9x cd boot -
the reason for this was that the INT 10h bios trashed some register
(DL?) and to a user it looked like the keyboard code was broken.
Have you tried to use a newer bios from bochs CVS?
