I'm using Microsoft Excel 98 (version 8) on a PowerBook G4 400 (OS 9.1). I have a file in Excel that I update every day (same file for about a month now) and is backed up every day. Tried to open it this morning and it won't. Opening from the finder opens Excel, then the file tries to load up, the progress bar gets about three quarters of the way across and then stops. I've left it alone for about 5 minutes but it just won't progress. Excel will force-quit OK and the rest of the System then runs normally. The same applies to the backup file. Everything was fine yesterday. Any ideas?
