All,

Wonder if any of you have seen this, and if so, know
of a solution.

Trying to do a very simple global notification to all
windows in case there is a state change in one of the
windows.

The simplest case is a toggle button which goes ON or
OFF.

However, with 2 windows, noticing a pretty severe
performance degradation (and ultimately hanging) if
the toggle button is clicked 5-10 times from each
window.

Any ideas?

Thanks for your help!

Cheers,
AM

code fragment:

var newSetting= "..."; // currently, "ON" or "OFF"

var obsService =
Components.classes["@mozilla.org/observer-service;1"].getService(Components.interfaces.nsIObserverServi ce);

obsService.notifyObservers(null, "am-setting-changed",
newSetting);

The observer looks at the value of the third
parameter, and sets its own window's global variable
to it.

There is also a shared-singleton-component that holds
newSetting; however, have commented it out to see if
the performance issue will go away, but it doesn't.
