portable thunderbird does not act as default mail client
I'm kinda having a problem with ptb: allthough I've set it up to act as the default mail client for the system (XP Prof), it does not act like that, i.e.: when trying to send files from desktop by rightclicking&sendto: mail recipient NOTHING happens. When trying to send from within openoffice writer, I receive an error message saying that there is no mail client defined.
What can I do?
Thanks
