Hi Adam,
Sorry I don't know if your previous answer is a reply to my question or to somebody else. Anyway, I have already removed the 'ICSharpCode.ShaprZipLib.dll' from the bin directory.
Let's me re-phrase the issue here: email hyperlink(mailto) is no re-editable once it is entered and saved for the first time.
I thought that's what another poster mentioned earlier in the thread.
Thanks,
Arnold
