311347 - If all Thunderbird windows are closed except the calendar, there is no way to show main Thunderbird windows again

Status: RESOLVED DUPLICATE of bug 309609

(Calendar :: Lightning Only, defect)

Description

[antoine]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7

Thunderbird:version 1.0.7 (20050923)
Language: English
Calendar:2005011112-cal

If you close all Thunderbird windows apart the calendar extension, you can't go
back to the main (inbox) windows or to other Thunderbird windows (Compose,
Address Book,...). Indeed there is no link in the calendar windows for these and
clicking on the Thunderbird icon does nothing as a Thunderbird window (the
calendar one) is still active. You have to close the calendar and then restart
Thunderbird...

Reproducible: Always

Steps to Reproduce:
1.Start Thunderbird
2.Open the Calendar extension (Tools>Calendar)
3.Close all other windows apart calendar.
4.Try to open Inbox, Compose or any other Thunderbird window.
5.Enjoy!

Actual Results:  
I am upset! I have to completely close Thunderbird and restart it to be able,
for example, to check my emails or write one.

Expected Results:  
Two options:
a) The calendar extension should provide a link in the menu to open inbox,
compose,...
b) When only the calendar window is open, clicking on the Thunderbird icon
should reopen the main window (inbox)

I use a basic install: English, default theme, default options...

Duping against bug 309609.  They're basically the same idea, that you can't 
open the parent application from the calendar window.
