I've just upgraded from Parallels Desktop for Mac 2.x to 4.0. I'm having trouble using the Knowledge Base because the articles are an undifferentiated jumble of 2.x, 3.x and 4.x entries. The Search function does let one specify a version but I don't see a coherent way to browse articles specific to 4.0. Or am I wrong? The closest I've been able to find is this page: http://kb.parallels.com/en/products/index.html?id=86 (This was particularly problematic for me because the 3.5->4.0 upgrade experience was so bad. I was seeing symptoms not covered in the standard troubleshooting guide and struggling through the KB and Forums desperately trying to find a match. From where I sit it looks to me like you guys rushed 4.0 to market without getting the bugs out of the upgrade process, including the documentation. I'm extremely unhappy. But that's another discussion.) Thanks.
