[galaxy-dev] iframe target links with external projector

Hi all; I'm giving a live demo of Galaxy in a few hours and was prepping with my laptop attached to an external projector. When connected to the projector, the target links in the sidebar load in the full window instead of targeting the galaxy_main iframe. This gets rid of the nice 3 panel layout. On the same machine the target links works as expected if my laptop is not connected to the external projector. Has anyone here seen the same issue when giving a Galaxy demo? Any configuration tips or tricks for Firefox (3.6) that will help? Thanks much, Brad
