SHSUCDX v3.04 bug (Users)

Hello,

playing with XCDROM32 I found a bug in Jason Hood's SHSUCDX v3.04 (dated 1. October 2006). When it is loaded without the /C option, there is a risk that it's local stack will corrupt other DOS upper memory blocks. The effects vary, depending on what has been loaded before SHSUCDX into DOS upper memory and how much of the stack is effectively used.

I reported this bug to Jason Hood, but since he's looking for a new maintainer it is pretty unsure that it will get fixed (soon). There is a workaround, instead of loading the driver with

INSTALL=SHSUCDX.COM

it should be done this way:

INSTALLHIGH=SHSUCDX.COM /C

MS-DOS forever!
