When I close the Oxygen XML Editor application with multiple files open and then restart it, every file opens in a split panel of the editing area instead of a tab sharing with the other opened files the same editing area which organizes the editors in a tabbed pane. I want to have the files arranged as a tabbed pane as they used to be arranged before closing the Oxygen XML Editor application.
This happens sometimes when several files are opened automatically on startup. It is a problem of the JIDE docking views library used in Oxygen XML Editor for docking and floating views. The workaround is to use the Reset Layout action from the Window menu.
