AV in Editor when switching connections

I had 5 tabs, 4 loaded from scripts. I successfully switched between sessions for 2 tabs several times but my last attempt resulted in this AV (if you need the full log file, let me know). It left my Editor window with the 'to" connection listed in the window title and the 'from" connection listed in the status bar (which was where the connection really was).

Just got an AV when exiting Toad, then Invalid Pointer, then a bunch of AV popups before it finally exited. This is in .76

All I had done since the previous AV was execute 2 scripts against 2 dbs. I had switches session within the Editor.

Just got another AV switching connections. Looks pretty similar to the one I’ve posted - different Read address. If posting or sending would be useful, let me know.
