Hi Serv... sorry I left to South Africa for a week... thank you so much for answering my post... Please see below my answers. 1- I am running Windows XP (version 5.1.2600) 2- I have no anti virus running anywhere 3- Yes indeed the parallel desktop resolution changes when I resize Parallels window 4- The share folders work fine, and I can acsess my mac hard drive using the shared folders or by setting up netwrok drives. both work fine. Only problem I have is when I hit the coherence botton nothing happens. It worked in the earlier releases but upon upgrading to beta 2 and beta 3, it stopped working. I have deleted everything from scratch, did a clean install, and reinstalled the tools and It won't work. Please help.
