[imp] IMP as Windows default mailer, attachments?

[Lukas Gradl]

Hi!

I'm trying to install Imp H5 as Windows default mailer.

I could register it as default for mailto links, but this only opens the 
compose window with the recievers address filled in - no message body, 
no attachments.

To fully replace the desktop mailer I would need to pass the message 
body to the window as well and automatically upload an attachment.

Is there any chance to do so? Is there any way to automatically upload 
an attachment?

regards
Lukas
