Which Ext version are you using?

[santoshsatav]

i am using ext 3.0 version

Ext 3.0 still had a bug in it's Ext.onReady code that could cause it to fail if you are using frames in Internet Explorer.

Would it be possible to upgrade to Ext 3.2 or 3.3? Otherwise you would have to replace the EventManager code in Ext 3.0 with the one from 3.2.
