357355 - Cannot open mail messages in new window after Lightning installed

Status: RESOLVED DUPLICATE of bug 357354

(Calendar :: Lightning Only, defect)

Description

[bugzil101]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

Installed Lightning 0.3 (build 2006100618) on Thunderbird version 1.5.0.7
(20060909). After the install, I was not able to open mail messages in their own window. This applied to double-clicking the message header in the list, or right-clicking and selecting "Open Message in New Window". Removing the extension resolved the problem.

Reproducible: Always

Steps to Reproduce:
1.Install Lightning 0.3 (build 2006100618) on Thunderbird version 1.5.0.7
(20060909)
2.Start Thunderbird
3.Right click on a message title and select "Open Message in New Window"
Nothing opens.

Actual Results:  
Nothing opens. The only way to see messages is in the message pain in the Thunderbird main window

Expected Results:  
The message should open in it's own window.

I never use the main window message pane. Removing the extension resolved the problem.

Uninstall/disable the old Mozilla Calendar extension as advised in the Release Notes and in Bug 357354 Comment #1 to solve this issue.

Marking this as a duplicate of 357354 since it does appear to be caused by that issue (not uninstalling the calendar extension).
