The nearest thing I have had to your problem was the computer running out of memory during calculations. It was a software issue where the program was using blocks of virtual memory on the hard drive, but forgetting to release them. It was not Lyx, but a Windows based CAD application. Keystrokes were being accepted but did not appear on screen for several seconds.
However with 16gb of ram available this should not happen to you. Gordon. On 19/12/13 08:38, David Belius wrote:
