Recently installed IE 9.0.8112.16421, in Windows 7 home.

Zoho Mail doesn 't function as it did previously in IE8 - right-clicking message no longer brings up "open in preview" option or any option that will open the message. Clicking or double-clicking the message does not open it. I have changed the viewing options for the folder to "open in new tab" or "open in new window" but no difference. Right-button menu options in IE9 have apparently changed. How do we open messages in IE9? I wish I could just double-click a message to open it in new tab or window.
