Hi

I've setup a Shared Workbook which is being used by 3 different users on a LAN. We are all up-dating the spreadsheet at the same time but have found that recently the spreadsheets keep crashing and the only way in is if one person un-shares the workbook and then person it crashed on goes in and shares it again.

Any ideas on what would cause this ? and even better, any ideas on how to prevent it from happening ?

Thanks.
