FireFox3 warning message

My application gives the message "Use of getBoxObjectFor() is deprecated. Try to use element.getBoundingClientRect() if possible." in FireFox 3.
It looks like this is originating in aw.js as it is the only javascript file using getBoxObjectFor in my application.

Just mentioning it here in case it has not been noticed before.
If you are not able to reproduce it, please let me know and I'll try to locate which AW call in my application produces the error.

Thanks,
Ankur

Fixed in 2.5.2
