Except for on initial load, any clicks on the left tree do not load a corresponding right side. Instead, the right is gray. The console reports this: [OPENED PREFS UI] we don't handle eBorderStyle_close yet... please fix me WEBSHELL+ = 4 nsXULKeyListenerImpl::Init() nsXULKeyListenerImpl::Init() WEBSHELL+ = 5 title string = [Preferences] *** PREF_onpageload('pref-appearance'); *** user prefs *** user prefs *** user prefs *** user prefs *** prefindex = 2; prefvalue = 2 *** prefvalue = true *** prefindex = 0; prefvalue = 2 *** prefvalue = false *** prefindex = 1; prefvalue = 2 *** prefvalue = false *** id & value: generalStartupBrowser : true *** id & value: generalStartupMail : false *** id & value: generalStartupEditor : false *** id & value: generalStartupCalendar : false *** id & value: browserChromeToolbarStyle2 : true *** id & value: browserChromeToolbarStyle0 : false *** id & value: browserChromeToolbarStyle1 : false [CLICKED AGAIN ON "Appearance"] *** going to save page data for tag: pref-appearance *** newURL: chrome://pref/content/pref-appearance.xul [CLICKED ON "Navigator"] *** going to save page data for tag: pref-appearance *** newURL: chrome://pref/content/pref-navigator.xul got a request [CLICKED ON "Navigator->Languages"] *** going to save page data for tag: pref-navigator JavaScript Error: TypeError: doc has no properties URL: chrome://global/content/widgetStateManager.js LineNo: 95 [CLICKED ON EVERY OTHER ONE, SAME RESULT:] *** going to save page data for tag: pref-navigator JavaScript Error: TypeError: doc has no properties URL: chrome://global/content/widgetStateManager.js LineNo: 95 [CLOSE PREFS, REOPEN] [CLICK "Mail and Newsgroups", THEN ANOTHER] *** going to save page data for tag: pref-appearance *** newURL: chrome://messenger/content/pref-mailnews.xul got a request *** going to save page data for tag: pref-mailnews JavaScript Error: TypeError: doc has no properties URL: chrome://global/content/widgetStateManager.js LineNo: 95 and so on for all the various items on the left. Although the end result appears similar to bug #19537, it's probably not related. The right side does NOT come back on a repaint. Occurred in todays nightly build (as in, I d/led it today, Jan 19).

looks like a dup of bug 24170... *** This bug has been marked as a duplicate of 24170 ***

verifying.
