Thanks - the substring functoid has now been corrected such that it will behave correctly if only two parameters are supplied, and we also found an unfortunate fixed reference to C:\Pop3Data as a temporary folder in some third-party source code we are using to parse MIME email attachments that we've worked with them to remove. Apparently this latter issue was largely harmless, although email processing may fail if there is no C: drive or the SmartsIntegrator service does not have write access to it. Both fixes are in 1.3.019, now available for download, and I have just tested email attachment processing, and aside from this issue it is working to specification.
Thanks,
Ben.
