Format of cells Changing on thier own
 

Hi,

I use spreadsheets daily and for months now I have been having an issue
where all my cells that are formatted as 'General' change themselves to
'Currency' when I reopen the spreadsheet.

Does anyone have any idea why this happens or what I can do to stop it.

Thanks.

P.S all of the workbooks are saved on a server and the problem is happening
on anyones PC who opens them.
