Have you checked that your mail server definitions are intact (Tools - Internet options)?

I'm using 4.61 & nothing happens when I select "check host for new mail."

Also, I have checked the user option "Ctrl+W activates the preview and selects the new mail folder" but it doesn't check for new mal & the Internet option "Check whenever the new mail folder is opened." This doesn't seem to work in 4.61 either.

Both of these features worked as expected in versions p[rior to 4.61.
