Signature's inline image disappearing when adding attachment

[maxxer]

Hi.

I've a problem with 6.0.7_GA_2473.
In my signature I have an inline image which is working fine. Using IE, when I compose a mail and add an attachment the image becomes a "not found" image.

This won't happen when using Firefox.

Also, I've this problem when I compose the mail using Affixa, the desktop client used to integrate in windows' shell.

Any hint?

thanks
