software problem with duo-core cpus

[Jeff]

I have an old application designed for Windows 3.1, which works fine in XP
home. Recently I purchased a new PC which uses XP MCE but has an Intel
duo-core cpu and the app freezes and will not run on it.

I have tried everything related to compatibility settings with no success. I
suspect the problem lies with the app's code which is incapable of working
with the advanced multi-threading of a duo-core cpu. Is there a utility
that will temporarily shut down one of the 2 cores or make the app believe
it is on a single core cpu?

If this application is very important to you, why not try Virtual PC
2004 (free)? You can install DOS and then 3.1 on top of it and the app
will be working in its native environment.

Never heard of it. I'll look into it even though it seems rather excessive,
but who knows. Wonder how much resources it takes up.

have you checked the BIOS or your manual on seting for just ONE cpu.
