Why does the browser continue to show connectivity activity?

[BlackBerry]

I am looking at some example codes of the EXT JS that is doing just some simple function calls nothing dynamic from servers. The icon for Firefox that shows internet connectivity activity is constantly spinning. Why is this the case?


Ext.onReady(function() {...});

This block of code in the onReady call is just referencing some sample functions. There are no calls being made to any external sites or files.

Is this the normal operation of Ext when using the Ext.onReady()?

Thank you for the insight. After reading the posts I tried the example in IE 8 and it does not have the issue of showing connection activity. This is a Mozilla engine issue.
