--- Comment #25 from Rob Shearman robertshearman@gmail.com 2008-07-11 06:41:37 --- Should have been fixed for a while now (in Wine and in cxoffice 6.0.3). Note that you need to use a backup of the file you tested with as the bug causes the loaded file to be corrupted and display the same error message when loaded again in Excel 2003 in Wine and on Windows.
