please help me. i just obtained a mac mini through my work. it was used on a touchscreen display to show an interactive brochure. it was going to get thrown out, so i took it. now that i have it home and hooked up,i turn it on and it goes immediately to nanopoint touch screen program showing the brochure. i can not figure out how to exit this program to get to the desktop. please does anyone have any ideas/advice to get this computer working normally??
