-ChangeLog:
-
-2002-02-25: bclary - modified xbDebugTraceOject to make sure
- that original versions of wrapped functions were not
- rewrapped. This had caused an infinite loop in IE.
-
-2002-02-07: bclary - modified xbDebug.prototype.close to not null
- the debug window reference. This can cause problems with
- Internet Explorer if the page is refreshed. These issues will
- be addressed at a later date.
