Problems creating default association for Yahoo mail

I have a new computer. I thought I had Yahoo installed on the new computer because I can send and receive email. But I cannot send an attachment or photo. "There is no email program associated.... Create an association in the default programs control panel." I have tried several different things such as regedit 32exe (and 64exe)/HKEY/clients/mail, etc., but cannot get past the "exe" part. I get the red X box telling me that an error occurred in opening the file. So then I tried start/default programs/set program association/non-Microsoft and Custom.

The problem is that "use current email" is already checked in the window which appears during the latter process. There are no other email programs to select, nor is there a place to type in another email program.

Thanks, A Guy. Although I dread having the Yahoo toolbar, I will give this a try.

OK. Toolbar is installed, but there is still no association established. I have discovered that I have no MAIL TO in my protocols. Is that the problem?

Would I need to change my browser to Firefox?

Wow, just tried to disable Yahoo toolbar, and my computer froze. Then I got a window telling me to contact my administrator. Brutal!

I would like to use Firefox, but there are so many things about it that I can't seem to get a handle on. Like that pale type, among other things.

Do you know why I wouldn't have MAIL TO in my protocols?

Thanks, A Guy. Yes, I did try Shawn's reg file. I kept ending up at the same place, no matter what I tried. It seems like it's the mailto thing that's the problem.

Meanwhile, down here on the ranch, Yahoo kept doing stranger and stranger things as the day progressed. I think installing and uninstalling the Yahoo Toolbar confused Yahoo's brain, and things started going haywire. My usual patient self just sort of said, "Way too much hassle to deal with you. G'Bye." I just notified my weary correspondents that I'd changed my email to one of my other accounts. Yahoo's a mess. I took the easy out! Thanks for all the ideas, however. :)
