Maybe it could be helpful, guys, if you listed your browser and perhaps even the platform you have (as in Linux, Mac, Windows). That could help track/exclude possible faults. :)
Or maybe not and I'm finally completely nuts.
Browser and Version # (can be found at Help > About IE/Safari/Firefox/Chrome/etc.)
Operating system / OS (Windows, Linux, Mac, etc.)
Version of OS (using Microsoft as an example, XP, Vista, 2000, 1998, etc.)
Also, check to make sure that you have the latest updates for whatever you have? That might or might not also be the problem.
