Crash of the Day

Received today from a colleague:

Please note that if somebody opens Build log excel in Microsoft excel 2007 and updates it while a filter put on any column, the file crashes.

So please avoid updating the build log in Microsoft excel 2007.

So we're talking about a fairy simple file created in Excel 2003 that crashes Excel 2007 if you try to update it while a filter is set on any column... Sigh...
