I think there are two problems here, which both Hagar and I are aware of from the Forum. One
is the Hashtag problem, which I agree is not readily reproducible and in many cases may be
caused by over hasty close down of OO or operating system, the other associated problem is
the erasure of the saved copy which seems to occur often alongside the hashtag problem; no
matter what causes the hashtag problem, I'm sure we all agree that a saved copy of the file
should not be spontaneously erased.
 
The question should be asked "When does OpenOffice erase the previous copy of the file?".
Surely this should only be after the Save process reaches a conclusion. I can recollect from
my CP/M days that one had to adopt a certain sequence in saving a file for best security.
One saved the file to File.new (say), then renamed File.org to File.bak then renamed File.new
to File.org. Is this or a similar protocol being followed in OO? Perhaps some temporary relief
can be obtained by changing the options in OpenOffice to _always_ generate a backup. 

If the user turns such an option off, then on his own head be the responsibility for file
loss!

I should say that I have not experienced the hashtag problem in 6 years of heavy use of OO
Writer on Windows 2000/XP or linux systems.
