I went on-site to check this out, and am still pretty baffled. It may have been a quick fix such as unchecking the Taskbar Autohide that I did last time - I am still kicking myself for not documenting whatever it was that I did at the time. All I know is that wasn't part of today's problem. After muddling about for awhile, I somehow added (pinned) links to the right-hand side of the taskbar - which gave me back the double arrows I was looking for. I dragged and dropped some shortcuts into it, basically building the list again from scratch. I eventually found the folder for Desktop Icons, which would have given me a pretty good list to drop into that - and may even have been what I did last time (although it didn't seem all that familiar). I am going to research the connections between the Links list on the taskbar and shortcuts - but if this rings any bells out there, I would love to know what the heck is happening here! Thanks for the input so far.
