I had two 7.0 windows running, each connected to a different, but both over a VPN. I lost connection and had to reconnect, which usually works fine. Tonight however, in one of the two instances of SQL Nav 7 there were no windows showing in the Task bar after the reconnect. All four code sql editor windows I had open at the time (each with multiple tabs) showed on the window menu fine, they just weren’t on the task bar. When I closed those and opened new windows, the new ones showed up on the task bar just fine.
As noted this did not happen in both instances, so it’s possible it’s not specific to the disconnect and re-connect, and that just happened to be when I noticed it. I can’t really think of anything else that was particularly different about either session however, or a task I did in one but not the other.
