Menu links not working in IE When I click on certain links in menu in IE a page with error message "Internet Explorer cannot display this page" appears. Other browsers are OK.

Problem is with these two links
"http://localhost/?q=calendar"
"http://localhost/?q=user/login"

Do you know what is wrong?

thank you
To give any meaningful answer you need to describe your problem better. I did notice that your urls seem to lack your site name

http://localhost/?q=calendar vs http://localhost/drupal?q=calendar

This can happen if you don't create the urls with the l/url function regardless of browser being used.
