I am not sure where to post this as there could be all kinds of solutions. I watch the NFL online, it comes via what I think is an embedded Java app for streaming. The problem is that the channels which broadcast the games (CBS/Fox) put an update banner at the bottom of the screen showing the scores of games other than the one you are watching. Over the course of the week I will watch many games and prefer not to know the result (living in the UK makes it easy to not be spoiled). The effect I would like to achieve is blacking out this banne. Some ideas I have are: Making an app which is just a black banner of x pixel thickness. This banner would be draggable and would have to be layered above the fullscreen Java applet which sits in Chrome Turning of entire lines of the display from say 750 to 800. Turning off entire lines in Chrome fullscreen (not sure if the applet would be affected by that). Hopefully you can see what I am trying to do, any ideas?
