Parallels is deleting negative Facebook-Postings, they didn't react on our posts in this forum - only two postings on page 1, where they told us that our Parallel Desktop 6 is useless and where they seemed to lie to us (because nobody here had heart about a free upgrade with lion). They want us to pay lots of money for an upgrade of something we payed for just one year ago. All my programs are working well with the m.l. upgrade - just P.D. failed. I can't support this kind of non-customer-care. I will not buy this upgrade but change to another program. This is really one of the worst ways to handle customer needs. Shame on you!
