Mea culpa. Mea culpa. I did not realize the distinction between "Beta Builds" and "Non Beta Builds".
As suggested by WINGDO (Many thanks), I have 'gone back' and reloaded Build 1970, and the Parallels that I enjoying using seems to be back. So thanks to Wingdo for pointing out my error. And thanks and apologies to Parallels. My previous post was, no doubt, an expression of my frustration. I'll skip the betas and wait for the next major release.
