It's really annoying to loose one hours work.
I would suggest that you enable the option
Save Autorecovery information and set it to e.g. 10 minutes. You find this in
Tools - Options - Load/Save.
That would at least mitigate the effects of a crash.
If you did already have this option enabled, then there might still exist a backup file of the lost document.
You will find the backup files in the folder
C:\Documents and settings\phil\Application data\OpenOffice.org2\user\backup
(supposing your windows user name (login name) being "
phil" and your system drive being C:)
The backup files all have the extension .bak. Just copy the file, if it's there, to some document folder using Windows Explorer, and then rename the extension to the original name, e.g. to .odt. Then you should be able to normally open the file.
NB: It is no problem if you use the wrong extension, e.g. .odp instead of .odt - OOo recognizes the correct file format.
But of course this does not solve your problem, which is not familiar to me.
OOo 2.3.1 is generally recognized as being quite stable. I experience crashes very seldom.
Did you do any special action shortly before the program hung up? Did it crash itself or did you end the program manually?
Maybe the document is somehow corrupted. Is this hanging reproducible? If yes, maybe try to save the document as .rtf and reload it - that may reorganize the document to some extend any maybe help.
Another idea is that your user profile is corrupt.
So you could try to create a new one. This is automatically done by OOo if you rename the profile folder.
This is done as follows:
At first, close OpenOffice altogether (also end the quickstarter in the system tray if active).
If your windows user name (login name) is "
phil" and your system drive is C:, then your OOo user profile folder is
C:\Documents and settings\phil\Application data\OpenOffice.org2
Now rename the profile folder to e.g.
C:\Documents and settings\phil\Application data\OpenOffice.org2.old
and start one of the OpenOffice applications again. Then a new folder is created.
You could also delete the folder, but renaming it allows you to rename it back in case this does not help (bringing you back your old settings which are lost when a new folder is created!).
Good luck!
