Looking for a little clarification here. Bug
37462 seems to address adding functionality to ZD so that a Windows user can either right-click on a document or within certain applications (MS Office for one) click File and select "Send To --> Mail Recipient" and it will work with ZD. There is also the issue of allowing a Windows user to set ZD as the default e-mail program, which would then open a "Compose" message window in ZD when a user clicks on a "mailto:" link within an email message, web page, etc. To me these are two different functions. Does bug 37462 address both things?
