I am on the current release of SQL Developer (1.5.4, build 5940). Every time I log into a database instance (doesn't seem to matter which instance), I get multiple code editor tabs. For example, if I log into an instance called 'ABC System', I'll get a tab labeled 'ABC System' and a 2nd tab labeled 'ABC System-1'.
It is not a serious problem, as I can delete one of the tabs and continue my work, but it is a bit of an annoyance. Has anyone else encountered this problem and know of a fix? Thank you very much.
