If PL/SQL Developer is terminated by the Task manager, it offers to restore the session insofar as that is possible on restart. However, that splash screen then becomes the 'icon' or mini-window for the application rather than the actual login pane. Just a minor annoyance... To reproduce, start PL/SQL Developer, open some objects, terminate with Task Manager, restart, accept restore, then use Alt-Tab to switch between windows. The restore confirmation screen becomes the window visible when switching between windows...
