ExtJS JsonStore partially loads data in IE6 and fails

Question

I have a JsonStore used by a ComboBox, and in IE6 it only partially loads the JSON. It cuts off after a point, which causes the JsonStore to fail. In FF and Chrome this works fine, and it even works if I run Fiddler..

I'm using ExtJS 3.2.0 and the webserver is a .Net Development server (vs2008) and runs locally. I've also found that this only happens when I lazy-load the store based on a trigger event. If the store is autoloaded, it works fine.

Has anyone else encountered this issue and have a fix?

Thanks!
