Can not resize libreoffice calc window - stuck maximized

Problem: A libreoffice calc spreadsheet file is stuck sort of maximized. It is not a normal maximized window and can not be resized and hides the desktop panel.

To reproduce:
1. From a normally opened libreoffice calc spreadsheet document, go to full screen (CTRL-ALT-J).
2. Save and close the file.
3. Re-open the file.
4. Opens in maximized window with no minimize or resize buttons, only a close button in title bar; no desktop panel.
5. Can go to full screen and out of full screen (CTRL-ALT-J), but problem persists.
6. Only affects files thus handled, i.e., made full screen and then closed.
7. Other libreoffice files open normally.

This problem has recently occurred with two operating systems: Mint 10 (Ubuntu 10.10), and Mint 12 (Ubuntu 11.10).
