We have recently set up a new PC for a client (approx 1 week ago) and installed Office 2010. Our client is experiencing intermittent crashes in Excel whist attempting to perform sort operations.
All of the workbooks are in the Office 97 - 2003 format. After doing some research I was led to believe that it's an issue with Excel 2010 and the .xls format, though we have tested the same .xls files on another PC at the site running Office 2010 with no issues.
So far have attempted rebooting, running a repair on Office, ensuring the latest updates are installed and disabling addons.
