Facebook channelUrl set but connect still shows blank window in IE7

I'm facing one odd Facebook connect issue, I'开发者_JAVA百科ve set up the FB.init method with correct params as mentioned in the FB developer docs - http://developers.facebook.com/docs/reference/javascript/FB.init/

Checked various places that mention, setting correct channelUrl will solve the issue, in my case i'm setting it correctly but still getting a blank(channel.html) popup only in case of IE7, is anyone else able to replicate this issue?

Any help in relation to this will be highly appreciated.

I've checked the protocol and all other standards related to setting this property but still no luck. Please help.

My apps get tested with IE7,8,9 and currently I'm not having any issues with a blank channel.html popup. What are the steps to reproduce this issue?
