Yes, the problem appears sometimes with Sky Demon Web. About Parallels, usually it is very stable, but sometimes I found the same problem when I suspend Windows. Closing it and restarting solves the problem.But anyway, with SD Web this issue appears in a random manner, not very frequently. I think really it is a minor issue, I mentioned it just in case there was some procedure to avoid it. As it is not the case, just forget it.
