If you installed another Web browser after installing Internet
Explorer and Internet Tools, some of your Internet Explorer settings
may have changed. You can reset your Internet Explorer settings to
their original defaults, including your home page and search pages,
and choice of default browser, without changing your other browser's
settings.
1.. On the Tools menu, click Internet Options.
2.. Click the Programs tab.
3.. Click the Reset Web Settings button.

[[OE Why can't I set OE as the default email client?
Why can't I Reply to Author in newsgroups?
Why do I see a Choose Profile window when I Reply to Author in newsgroups?
All of these problems indicate that OE is not properly configured as the
default email client on your computer. To be sure OE is the default mail
client, close OE, click Start | Run and enter this command line, complete
with quotes, spaces and the /reg switch:
"C:\Program Files\Outlook Express\msimn.exe" /reg
Of course change the path if you installed OE elsewhere.
Now click Start| Settings| Control Panel, double-click Internet Options,
then click on the Programs tab, and verify that OE is now the default email
client. (You can also get there from the IE Tools| Internet Options menu).
Then open OE and click Tools| Options, and at the bottom of the General tab,
verify that OE is set as the default. If it is, the "Make Default" button
will be grayed out. If not, click the button.]]
