Excel freezes when opening a Linked Spredsheet
 

User tries to open a spreadsheet which has links to other spreadsheets and
pulls information from them. When it is opened a message box appears asking
to update the spreadsheet, the user does this and excel freezes and stops
responding. If it is opened without updating it opens fine as do all the
other spreadsheets which have links. I have tried open and repair on the
various spreadsheets with no success.
We are using Excel 2003 and all spreadsheets are stored on networked drives.
