Has this issue been solved? I opened Parallels to work on developing a Windows app, and I was greeted with "new version is available , upgrade now!" First I thought, "I'll just install the free update." , but I kept reading the advertisement. The small print said "free trial for 30 days, then you have to buy it." That is pretty slick marketing, Parallels! In a sleazy deceptive way. It's also the last straw. I'm moving to VMWare Fusion.
I see this thread has been open for years, assuming Parallels won't get of rid of this then, so I guess I'll just shout into the void how pathetic this is.
