I have Win 7 64bit system. Just downloaded latest version of ImgBurn and installed it. Clicked destop icon, up came the program, I burned some photos to a CD, great software. Problem occurred when I went File / Exit nothing happened but the message on the software screen LH lower said 'saving settings' and it kept on like this till 'Not Responding' was seen in the top RH of the software screen, followed by a warning box giving me the option to close or to wait for the software to close it. Did a quick Ctrl / Alt / Delete and the task manager showed it was not responding, so I ended it. Done an open and close exercise twice more, no luck. Any help much appreciated.
