Overview: Sometimes changes to a Macro, in either a Module or in a Dialog, are
not saved when the document is closed (with Save).

Analysis: This appears to happen if (1) the 'Save AutoRecovery information every
__ minutes' option (Options -> Load/Save -> General) is turned on and (2) an
auto-save action takes place prior to (a) Closing (with the Save option) or (b)
manually saving the document (e.g., File -> Save or ctrl-s).

Example:
1. Ensure the Save AutoRecovery option is turned on.  For convenience, set the
time value short, like 2 to 5 minutes.
2. Create a new document (spreadsheet and text documents have been tested). 
Create a Module (Module1 by default).  Save the document.  Optionally, open an
existing document that contains a Module.
4. Modify the Module (for example, add a comment).
5. Wait for the autosave action (indicated by a 'saving' message in the status
bar, which can be very quick in a simple document and thus difficult to see) or
wait at least as long as the autosave minutes option is set to.
6. Close (Save) the document).
7. Open the document.  Look at the Module.  (The change you made is probably not
there.)


Comments:
This also occurs for Dialog changes.
This also occurs with previous versions of oo (2.0, 3.1.1 tested).  (I'd had
auto-save turned off while using version 2, so I didn't discover the problem for
some time.)
This occurs on at least Windows and on Linux.
Auto-save does save the changes.  This can be seen if the process is killed
(after auto-save takes place); the restore process, on the next OO startup,
shows the change.

Workaround:  (1) Turn off auto-save, or (2) execute a manual Save immediately
after changing a Module or Dialog.  (Probably still fails if the auto-save takes
place between the time you make the change and the time you save it, but that's
hard to confirm.)

Further notes and possible appologies:  I have no idea what subcomponent
applies, or even what the various options mean; since it's required, I merely
selected the first.  As a first time issue submitter, I find the process not as
straight forward as I might hope.
