jmathies, should this block? I wonder how this could interact with Panorama or session restore.
(In reply to comment #1) > jmathies, should this block? I wonder how this could interact with Panorama or > session restore. I don't think so, it's passive. Just an extra icon on the taskbar when flash is in full screen mode on dual monitor setups. We could touch this up by adding the fx icon to the plugin container exe or better, find someone with a setup like this to work on it.
We actually fixed this for the single monitor case AFAIK, we propagate the app modal id over the secondary process. It's tough to test to see if that's working though.
