I pressed Ctrl – on Toshiba portege and a thin lined circle about 2 inches diameter flashes for about 1-2 seconds, decreasing in size in smaller circles until it disappears – any idea what this is and why?
I want to make it impossible to use key combinations to start up hidden programs or any function. Eg, if someone gets access to my lap top and installs a program I'm not aware of, then uses certain keys to access it when I'm not around. How do I prevent this? I am happy to disable them. I've read through the Toshiba manual but still can't work this out. Thank you.
