Junk controls in the standalone message window either die silently or throw this error: Error: JunkSelectedMessages is not defined Source File: chrome://messenger/content/messageWindow.xul Line: 1 When I debugged it with Venkman, executing controller.doCommand("button_junk") while being in goDoCommand(), I got this exception: Caught exception: “[Exception... "'[JavaScript Error: "JunkSelectedMessages is not defined" {file: "chrome://messenger/content/mailWindowOverlay.js" line: 1438}]' when calling method: [nsIController::doCommand]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" location: "JS frame :: x-jsd:interactive-session :: goDoCommand :: line 1" data: yes]” So somehow the functions in junkCommands.js seem to be missing in the standalone window.

Seems like SeaMonkey includes junkCommands.js only in messenger.xul, while TB includes it in mailWindowOverlay.xul, overlaying both messenger.xul and messageWindow.xul...

The patch moves the include of junkCommands.js from messenger.xul to mailWindowOverlay.xul, making the junk commands available in both the 3 pane view and the standalone message window.
