Outputting error messages in a browser?

Question

Is there a way to output all error messages to some sort of
window when viewing a SWF in a browser? I'm working on a game and
I'm about to beta test with a few dozen people. They will do this
by playing the game in a browser. Sometimes the game crashes and it
would be great if the error message that accompanies the crash
could be shown, so they can copy and paste it to me in an email.
This way i dont have to play the game over and over in the flash
IDE to try and re-create the problem.
I know you can output trace messages to a javascript window,
but what i need to do is output ALL error messages to a window of
some sort. Any ideas or advice would be appreciated.

Okay i answered my own question. For anyone who is looking to
beta test their SWF with other people, this might be helpful..
everything in the program is controlled by one mainLoop
function. so i just enclosed that mainLoop function within a try {}
statement. then right after that i did:
catch (e:Error) {
//some code that puts the String (e.getStackTrace()) on the
screen
e.getStackTrace() will create a string that gives you the
detailed error message. HOWEVER... this will not work within a
browser. it will only work within the standalone flash player. so
i'm just going to have people download that stand alone player and
beta test the game outside the browser. or create a
self-executable.
if you need to have it within a browser, i think the most you
can get back for an error message is the type of error (example:
ReferenceError 1069). you can get that by showing e.message or
e.toString(). i cant seem to get it to pass any more information
about it. and when the program is huge, those errors arent very
helpful.
