Hmm. Not sure why that would happen. Do you recall what the object types were?

That's basically how I've been testing it. I wonder if you're getting
confused by the fact that not all object types will access the
database when clicked (and others won't access the database if they've
previously been clicked or expanded), thus won't necessarily cause a
connection check to occur.
Do you see any cases where the connection isn't checked and bad things
happen? Or just cases where you expected a check, but don't see one.
BTW; thanks to both you and Jasmin for testing.
