Session stop reason: negotiating failed, bad dpi value

This only happens using FireFox v18 and the Ajax Client

It does not occur when using Accesspoint with FireFox

Using IE or Chrome My Web app works perfectly

We have an MVC application that allows user authentication to our application, once the user logs in and selects a dashboard (that's available to that specific user) we launch the following url:

http://Servername/QvAJAXZfc/opendoc.htm?document=Somthing.qvw&host=QVS@SomeHostName&anonymous=true

QlikView 11 SR2 Build 11440

Thanks

I forgot to mention we are running QV Ajax under IIS7.5

And testing on Fire Fox v6.0 shows that the problem is still there BUT less frequent

Also we are rendering the documents within an iFrame:

      <iframe width="100%" height="100%" src="http://Servername/QvAJAXZfc/opendoc.htm?document=Somthing.qvw&host=QVS@SomeHostName&anonymous=true">
