I wasn't doing anything in particular when this occurred (keeps occurring). Just reading text, scrolling up and down, and moving from tab to tab. I have never had any problem with LOGOS on this computer before. It always runs very well/fast. Now it just locks up each time shortly after opening the programs and clicking on a few tabs and/or scrolling. The only way to close the program after "not responding" is to open the task manager and close it by clicking "end task."
