I currently owe a Macbook with 2 GB of RAM installed. I have used Parallel Desktop to run Windows XP along with OS Tiger for over a year without any incident. However, recently I upgraded from Tiger to Leopard. Ever since then Parallel Desktop have been responding weirdly. Over half the times when I attempt to open Parallels Desktop the application would fail to respond and my computer would behave extremely slow until I force quit Parallels. On the times that Parallels actual successfully open, the internet in Windows XP would not connect. Even if I'm connected to Wireless or Wired networks in Leopard. This problem is getting quite frustrating and any help would be greatly appreciated. Thank you.
