WetGeek I have work to do that requires the browser.
Once again, I started all the applications except the browser in their workspaces, and hibernated. Upon wakeup, everything is working normally. I'm sure that if I hibernate again, a wakeup will once again work without error, and that's what I intend to do now for as long as I can. I.e., I'll hibernate this laptop every night, as usual, and see if I can keep it working without errors for the rest of the week.
Maybe the next sync will produce a pleasant surprise, and I won't need the work-around any more.
