let me across another issue.
If I type in a non-existent database in connections manager it actually displays in Object Browser. See attached. I absolutely have no database named 'blabla' ! An attempt to open it removes the '+' sign and no more.
Another similar issue is that if I have a user that has privilege to 'somedb' only and let this user connect with SQLyog specifying 'someotherdb'. 'someotherdb' displays in Object Browser (no matter if it exists or not)
Both will be very confusing if people are not aware of the reason for this!
I suggest a pop-up like 'No Database “blabla” found or User has no Privilege to Access It' .
