Why does my GXT App Hangs When not in "Compatibility Mode" in IE8?

[blackbox23]

Hello,

I have a GXT intranet app built using GXT 2.1.1/GWT 2.0.

My problem is in IE8 the App just hangs on the "Loading Application" Loading Panel when "IE8 Compatibility View" is not turned on.

When I set the Compatibility View, the app refreshes and proceeds with the Login window Panel.

Could someone help me out regarding this issue?

Thanks in advance.

Is there anyone who knows whats causing this? Id like my app to work regardless whether the Compatibility is On or Off.
