Working with OOo Writer pre-3.2 (DEV300_m60) on Windows XP SP2 Russian, I have
discovered and steadily reproduce the following problem.

I transferred my user settings from OOo 3.1, including autocorrect lists that
are currently in my c:\Documents and Settings\<user name>\Application
Data\OOo-dev\3\user\autocorr\ directory, as they should be. When I want to add
an entry to the list, I proceed as follows (worked with previous versions):
1. Select a text that I want to make a replacement option.
2. Enter Format → Autocorrect → Autocorrect Options.
3. In the Replace tab of the dialog, I see my text in the With: field, choose
the language from the drop-down list (for example, Russian), type in a shortcut
into the Replace field, tick Text only, click on New.
4. I see the entry added to the list.
5. I close the dialog and continue editing. The new autocorrect shortcut and the
previous ones work fine with the current document.
6. But after I close the document, all entries are lost and the respective file
(say, acor_ru-RU.dat) becomes zero-size. Any other autocorrect lists available
remain, unless I try to modify them.
7. Whenever I restore a .dat file from my OOo 3.1 profile or try to create a new
list from scratch, it all happens again: any previous and/or newly added entries
are retained for the current editing session only and are erased after closing
the document.

I have admin permissions on the computer, so there is no problem with read/write
access to the files.
