Shared files formatting problem

[induadhikary]

I have a problem sharing a workbook file. we are about 12 people sharing this file and we all use Ms office 2007. One of the users can open a the file but if she modifies and saves the file .. next time she opens the file Excel claims there is a problem with the format, preforms a recover action on the file, and then closes. The next time any [COLOR=green ! important][FONT=inherit ! important][COLOR=green ! important][FONT=inherit ! important]excel [/FONT][COLOR=green ! important][FONT=inherit ! important]file[/FONT][/COLOR][/FONT][/COLOR][/COLOR] is opened Excel shows the recovered xls document minus the formatting. This issue just started happening, the file has been shared between the users for about a year now. The new file has stripped all date and currency formatting. i created that file , because of that problem i unshared the file and edited the format and made it shared again, the same problem , the formatting,. Header footer, pane freeze, print layout, ......does not work for everybody. it works only for me. Pls help me thanks--
