How can I stop Document Viewer from always opening full-screen?
Solution 1:
Converting Volodya's answer as a comment to a complete answer:
You probably changed Document Viewer's default settings by accident. This is an easy mistake to make, since the keyboard shortcut for doing so is the same as for opening a tab in your web browser, and you frequently type into the wrong window as a result of the lag in Unity's window switcher.
To correct the mistake:
- Exit the full-screen view by pressing F11 or unchecking View ▸ Fullscreen.
Save the current settings as default by pressing Ctrl+T or selecting Edit ▸ Save Current Settings as Default.
This won't affect documents you've opened previously until you reset the stored settings for those documents.
