Running an app in a separate XP account whilst using another XP account?

[furman]

Hi,
I have 2 PCs, 1 is mine the other is my business PC which has an ecommerce app which checks for orders at a set time say 20 mins.

I want to get rid of the business PC and put the HDD in my PC but add a separate XP account which will allow the app to run whilst I am logged in with a separate XP account on the same PC. Can this be done?

I haven't tried it yet. The software is Actinic Business, I don't want it running on my main account as I always get someone using my PC.
If I take the HDD out of the other PC - its just got Actinic installed on it, do I need to reinstall actinic for windows to recognise it (for any reason) or do I just install the disk into this pc?
