When trying to compare two capture-files (following this article I get an error-message when trying to run the compare. It seems that the filter-value is pre-populated even though I haven't selected anything.

The error-message I get is: Filter "000000" is invalid - "000000" is neither a field nor a protocol name.

If I click OK and try to apply a filter, I get the same error again, but this time it might look like this: Filter "000000, eq 1139" is invalid - Syntax error.

Version/OS: Version 1.4.1 (SVN Rev 34476 from /trunk-1.4) Running on 64-bit Windows 7, build 7600, with WinPcap version 4.1.2 (packet.dll version, based on libpcap version 1.0 branch 1_0_rel0b (20091008), GnuTLS 2.8.5, Gcrypt 1.4.5, without AirPcap.

Anyone seen this problem before and found a resolution??

Did you have 000000 in the Filter: box in the main window? If so, then that will be copied to the filter box in the "Compare" window (you can edit that filter box and remove the copied filter).
