How to run multiple instances of whatever program you want in Win XP
Had the same problem getting dc++ running in two instances. Different hubs, different share rules, so it was a pain in the *ss. One solution I found is to install dc++ in two different locations. Make a shortcut for each of the locations on my desktop(or wherever..)
Then, run the first instance the normal way, by double clicking it. After that you rightclick the other shortcut and select the "Run as.."-option.. this'll let you run a second application for each of the users available on your comp. If you're the single user the only available other user will most likely be Administrator, just enter your password and weee... up pops another instance of dc++
