Yes of course.

Two tiny problems though:

1. your little scriplet doesn't work for me. I get:

'W.frames.2.location' is null or not an object

2. If as you claim this is "standard practice" then there is 
something wrong with these browsers as it apparently does not 
work on them:

The following browsers are not affected:
* Mozilla Firefox 0.9 for Windows
* Mozilla Firefox 0.9.1 for Windows
* Mozilla 1.7 for Windows
* Mozilla 1.7 for Linux

Perhaps someone who really knows will enlighten us all.
