A while ago I was looking through a PDF on Adobe Reader 9 when it suddenly stopped responding. I tried to close it every way I knew how but it would not close. I tried clicking X, right clicking the task bar and clicking "close" I even tried using the Task manager to "End Program" and while I was able to use the Task manager normally the "End Program" button effectively did nothing. I did notice that my CPU Usage was jumping between 50 and 65%. I eventually had to manually restart my computer to get it off. Anyone know any solutions in case this happens again?
