Actually, I had another problem, the mailto: links in Firefox also opened the Inbox, instead of a Compose window. I have resolved both of them--here is how:
- Under Firefox->Tools->Options->Applications->mailto there is a drop-down box which (for me) selected [Windows Mail]. However, there was another selection: [Windows Mail (default)]. When I made this selection, both of my problems went away.
- I don't really understand it though, because there is an option called (Application details) and both of them read:
This application is located atNothing about email parameters like subject or body.
C:\Program Files (x86)\Windows Mail\WinMail.exe
Bear in mind that I had already managed to make Windows Mail the default in Windows 7.
