I remember a few weeks ago it was reported that there was a conflict if someone ran the Peerunity and Peercoin-Qt clients on the same computer and/or at the same time
We are presently offering the clients with no explanation about this - is the problem fixed, or should we be providing a warning?
Since the use the same default data directory, I think there should be problem if both are trying to open the same wallet (if the lock file didn’t stop the second client to start).
I use both on mac and you can only open one client, so if you don’t want to run them at the same time there is no problem.
