Netbook Screen Resolution Changer
I've finally found a screen res changer that works with a hotkey: Netbook Resolution Customizer
I needed something to do this as one of my schools want to run CrazyTalk (which only runs on 1024x768 and above) and to change to that mode required a lot of key fiddly mouse movements/key presses.
With this utility, I've set it do Alt-PgUp switches to 1024x768 and ALt-PgDn goes back to normal 1024x600.
I've enabled the downscaling as well but I'm not sure if the squashed display will be suitable in real use with pupils - I'll need to experiment.
Its got the facility to auto change resolution depending on program run but I haven't got it fully working yet.
