I think we have a problem with the uploading of files from the web form.
Could you just send a message to address@hidden with the
attachment?

We are about to release the 1.2 version of IDV on Friday.  I'm thinking
that this has probably been fixed in that release, but would like to check it.

Thanks for the details.  If you send me the file again, I'll check it
with the latest release.

I apologize for the problems with the attachements on the web form.
