BugSeeker's GUI operates in two modes: a source view and a debug view. The debug view appears automatically whenever a debugging session is activated. In the debug view, the main window is horizontally divided into two panes; the source viewer, which occupies the top part of the window, and the debug pane, which occupies the bottom part of the window.
When a debugging session ends, BugSeeker will switch back to the source view because you no longer need to view the debug panes. The source-only view offers more room for you to view your source code by eliminating the debug tabs that would otherwise clutter up the display. BugSeeker will also switch to the source-only view if you switch to a project that does not have any debug sessions active for it.
If for any reason you would like to switch between the two views, select View | Debug View to toggle the debug view on or off.
