No matter what I do, I cannot get the program to capture the entire screen. Even when I use the redbox mode, it will only capture about two-thirds of whatever I have in the box. I have continued to use the program, because I generally do not need to capture the entire screen. I manipulate the size and position of the screen so the program will capture the area I want, and then I crop it to get what I want before I save it. This takes a little time, but it gets the job done when you don't need to capture the entire screen.
It just seems to me that the program will only capture a limited resolution. I have a 24 inch screen with a 1920 x 1200 resolution. I do have the screen view enlarged somewhat in my browser, because the native resolution makes everything so small, I can barely read it. Perhaps that is causing the problem, but without the program running, the Print Screen key does capture the entire area of the screen.
FYI, I'm running Vista, 32 bit, and my browser is Firefox. My computer is fairly new, and I've got 4 gigs of RAM.
