Ctrl+Shift+D for Open Database Object doesn't work in 1.5.1
Ok, i have found the reason. In then preferences dialog keys->"Open Database Object" then input field "When" (in the lower left corner) contains "PL/SQL". In release 1.3.1 the value is "In Windows". When i switch to "In Windows" the function works.
After a new installation in another eclipse all works fine. I close this thread.
