This is supposed to be used to check if your LCD has dead pixels,apparently...
Please consider adding some instructions like how to quit the app with some shortcut keys since it works in full screen mode(i have to quit it with option-command-esc,i tried to use esc only but it doesnt work anyway),and if the menu can be set to Auto-hide it would be perfect

Thank you for your review.

There are two "best" ways to quit the app.

1. You move the mouse to the top corner of your screen, the menu bar will appear and you can quit like you normally would using a non full screen application.

2. You can quit with command-q which is the standard for quitting apps.

3. I wish I was any good at creating Icons, I am not, therefore the app is without an icon.

If you are capable of creating a stunning great looking icon, let me know, and I will add the icon to the app.

Thanks for letting me know that it runs on Lion!


Thanks for your quick response, i have checked again and indeed the app can quit in both ways as mentioned .
Unfortunately I'm unable to provide you with the icon, hopefully you may get it from others
