I have several large Excel (2003) workbooks, which are linked.
I open A.xls in Excel 2010, then open B.xls from Edit->Links. This works fine, and I can use B.xls.
If I then close B.xls, and try to open it again (either from File->Open, or Edit->Links), Excel claims the file is corrupted and wants to repair it. Opening the same file from a different Excel instance, or different computer, works just fine, but in that Excel instance, I can never open B.xls again. Closing everything lets both files be opened just fine, unless I close B.xls again and try to reopen it.
I've tried searching for answers, but I haven't been able to hit the exact combination of keywords that give me an answer, so I don't know if this problem is wide spread or not. I can reproduce it 100% using the same two excel files, but it doesn't happen with all files.
