I'm trying to use Adobe's "Send for Signature" function, inside the Laserfiche viewer - has anyone got this working?

I get an error when trying:  "Could not complete your request" - this is within the Plugin in laserfiche.

Also:  Is there a way to stop laserfiche viewer with Adobe reader plugin from renaming the temporary file?  They are currently being assigned a temporary name (eg: led9631.pdf)

Thanks in advance,
