Faulting application EXCEL.EXE, version 11.0.5612.0, faulting module EXCEL.EXE, version 11.0.5612.0, fault address 0x000a9df2. We have a client with a spreadsheet that crashes on Save / Save as or when trying to break a link to another spreadsheet - both spreadsheets were created with Excel 2003 SP2. I f you copy each individual sheet (5 sheets) from Spreadsheet 1 to a blank spreadsheet - new spreadsheet 1 (5 sheets) it's fine - Save / Save as. The linked spreadsheet - Spreadsheet 2 works fine all the time when it's linked to Spreadsheet 1 or not linked - Save / Save as. As soon as the two are (new spreadsheet 1 and spreadsheet 2 ) linked and you open the new spreadsheet 1 you get the message that "This workbook links to other data sourses" Update / Don't update / Help Even if you don't Update the links when you Save / Save as / or try breaking the link and Save MS Excel Crashes: Microsoft Office Excel has encountered a problem and needs to close. We are sorry for the incovenience. Debug does nothing - Send report - sends MS a report - I have tried different PCs and different versions of Excel 2000 /2003 - Same issue. Mike

First, I assume that when you say "copy each individual sheet (5 sheets) from Spreadsheet 1 to a blank spreadsheet" you actually mean "copy each individual sheet (5 sheets) from Workbook 1 to a blank Workbook". A workbook is a collection of worksheets. With that assumption made, how are you copying the sheets - with a right-click of the sheet tab and choosing Move or Copy... or by copying the data by selecting all cells and doing a Copy/Paste? Whichever method you're using, try the other. It sounds like you are copying the corruption from one workbook to the other workbook, so maybe switching to the other method won't. Another thing to try is to copy the sheets one at time and then doing the Save. You might be able to narrow it down to the sheet that's causing the problem. Once you've done that, start copying the corrupted sheet in sections. If you are lucky, after a few tries you'll be able to narrow it down to the single cell that's causing the problem. Been there...done that.
