default mail client?

[STG]

When I try to reply to an ad on craiglist I keep getting a warning that my default mail client is not installed properly? I have no idea what this means? When I click ok i get about 35 windows that pop up and it closes me out of windows. Anyone know how I can fix this? It only happens on craigslist.com.

Are you using Internet Explorer? From the menu go to Tools > Internet Options and in the new window go to the Programs tab.

Check to see what the mail program is set to be.

[STG]

Yes, I am using internet explorer. I will check tomorrow.
What is it suppose to be set at?

[StevieG]

It should be set to whatever Windows program you use for email.
