After upgrading to Parallels 3.0 using the program makes my computer unusable. XP takes forever to open and then is realllllllly slow to do anything. When going to use Apple programs many stop responding or are very very very slow. It makes my computer so completely slow it was like i was using an old SE! LOL But seriously I cannot use Parrleles and windows like this. I have tried to contact support 3 times with no response. Have looked through the forum to a point to find a soultion. Parallels 2, the last version before upgrade worked perfect. Only since upgraded to 3 have had this problem. I have a Macbook bought last year. Intel 1.83 Cre Duo 1G memory Please help!!!!!
