Problem solved and it was a problem in Windows, not with OpenOffice.org 1.1.5:
Start -> Settings -> Folder Options (or whatever it's called, in Swedish it is "mappalternativ") -> File Types -> URL MailTo-protocol -> Edit -> Select "Open" -> Edit -> Set program to Opera (in my case) by pressing the Browse button and select the Opera.exe when found it. Maybe I need to edit that a bit too, since it doesn't work for 100% like expected. It actually opens three tabs in Opera of which one is the one I am looking for... but I will find that out sooner or later... Johnny
