I am new to Zimbra and haven't found an answer to this question. Is it possible when reading mail in Zimbra to open up each message in a separate window by double-clicking on it?

I right-click on messages and don't see an option to open the message in a separate window. But, much like how you can write a new message in a separate window, I'd like to be able to open up individual messages in a separate window to view them.
