Default e-mail client

[premier69]

I have a small inconvenience on my hands.

I have outlook 2007 installed and set as my default e-mail client on my system but when using certain Vista functions like right-clicking on a file in explorer and choosing the "compress and e-mail" function it does use 7zip to compress it into a zip file and then opens the wrong e-mail client to send with, it pops up the wizzard for creating an account in windows mail.

its the same thing when using the windows snipping tool, taking a screenshot and then choosing the programs function "send snip" as either an e-mail or an e-mail attachment.

I suppose it's a question of a registry fix or something?
