Cannot activate tracker if local caching of urchin.js is turned on

This is probably just a user interface issue, but I found that Google could not detect that my analytics was properly installed on a site while I had urchin.js cached. As soon as I turned off caching, it picked it up just fine. You may want to clarify this in the user interface.

Here's the current text below Cache urchin.js locally:
If checked, the urchin.js file is received from Google Analytic and cached locally. It is updated daily from Google's servers to ensure updates to urchin.js are reflected in the local copy.

I suggest adding the following text: Do not activate this until after Google Analytics has confirmed your tracker.

https://www.google.com/support/googleanalytics/bin/answer.py?answer=5548... suggests that Google wants to see the exact code they give before they will confirm the tracking code is properly installed on a site. Turning on caching disrupts this process.
