Hi,

Thank you for your email. This is a know problem and an IDE has been
released recently to fix it. Please make sure you are up to date with the
latest version of Sophos (3.70, soon 3.71) and all the IDE files from
http://www.sophos.com/downloads/ide/. If you are still having the problem
please forward a copy of the file in question to support@sophos.com and we
can have a look at it in our lab.
