Internet Explorer 9 in Windows 7 Home Premium 64-bit has the items Send Page by email and Send link by email grayed out. The default email client is Windows Live Mail 2011. I have used the "Set Default" dialogs to do that. Everything else recognizes Windows Live Mail 2011 as the default, including Firefox 4. I have duplicated this problem on two computers here. I have changed the default email program to Mozilla Thunderbird on one of the computers, and IE9 won't let me Send Page by email or Send link by email there, either.
Has anyone gotten this to work? Firefox is my default browser, but sometimes I have to use IE9.
