PartyPoker & PokerNow Software conflict

[Larimani]

This is a very strange issue. I have installed both partypoker & pokernow clients on my PC. When I try to start them seperatly they both work without a glitch but it I try to open one of them while the other one is already open, they won't open! Instead the other client will just come into focus!!

For example partypoker is already open; I try to open pokernow... pokernow won't start! instead it will try to open partypoker & because it's already open it wil justt bring it into focus...! strange... anyone else get that?
