What the heck is a "Too much Recursion" Error

.But now i have ran accross another problem with this Mozilla 1.6. I added a button for to select some preformated text... but on the Solaris Mozilla.. it give me this error:

Javascript error: Chrome://global/content/globalOverlay.js Line 50
Too much recursion

and then the CPU goes to 100% Util and you have to kill the browser...

I can not repeat this error with firefox or IE seems to only happen on the solaris Mozilla 1.6 ...

I hope you can get the error i was getting.. not sure if anyone has a solaris machine to test this... BTW... some things I have removed from this page due to the sensitivity of the info. THe key things here is the Classification Indicated by the Red "C".

Suggestions?
