Hello, I too have a Dell M6400 with an Nvidia Quadro graphics card. I have the same issue as Bill - no panel titles with the QAT on top in Navisworks 2011
Thank you for your question.
It looks like a known issue about windows DPI setting. In Windows7 and Vista, user can set custom text size (DPI), but Navisworks 2011 doesn't support such setting. You have to use the default size (100%) to open Navisworks.
This issue will be fixed in Navisworks 2011 Service Pack and future release. You can update your Navisworks later to see if this can solve your problem.
Please let me know if you have any further questions.
I installed SP1 today and my ribbon and QAT are functioning normally. Good job guys!!!
On another note, I cannot locate the Subscription Advantage Pack for Autodesk Navisworks 2011 up on Subscription Center. I see the videos and links from the Navisworks Support page and Beyond the Paper blog but, no Pack on SC!!!
