This may seem stupid and crazy, but, I have my email and folders all set up good. Yesterday, I set up my calendar and closed the program. Today, when I clicked the Thunderbird icon...the calendar shows...which is fine, however, there is absolutely no way to get to my email view or tab from here. I checked every menu item, every customizing option and even the "Go" menu has no way to get back to the mail view. I also tried right clicking on the tabs with no luck. How do I get back to my email view? Thank you.
