Thank you for checking, Corrine.
If I continue to get the odd error messages will post about them here as the board permits or tell G via another site. To get my last post (above yours) in this thread, I tried several times in quick succession.
Of course, now that the question about tray icon colors is resolved, it's likely to be awhile before I need to post here again. WinPatrol has been very stable over the years.
