Status: RESOLVED DUPLICATE of bug 485268

(Calendar :: Calendar Frontend, defect)

Steps to reproduce:

While viewing a Thunderbird instance that shows a Mail tab and Calendar tab....
Right-Click on the Calendar tab or the Mail Tab.
From the context menu that appears, select any of the following....
-Close Tab
-Close other Tabs
-Move to New Window

Actual results:

-Close Tab does nothing on the Mail tab, but closes the calendar tab if used there.
-Close other Tabs does nothing unless you are over the Mail tab
-Move deletes the existing Calendar tab, then creates a new window/form with a mail tab and a Calendar tab.

Expected results:

These three results are non-intuitive for the following reasons:
-The Close Tab implies that it will close the existing Tab. It does not work on the mail tab, so it should be greyed out to prevent use if the mail tab can never be closed.
-The Close other Tabs item should be grayed out if the only other tabs are mail tab and it cannot be closed.
-The Move to New Window implies that it will move the selected tab (Calendar) to a new window with just a Calendar tab. It does not. If performed on the Calendar tab, it creates a new window with both a mail and a calendar tab, yet still deleted the old Calendar tab. This is non-intuitive.
