I have been using ESS on my main computer for some time. The cpu usage is always low since I disabled the auto update on the hour. I still get updates via initial dialup which keeps all my definitions to the latest versions. But now I have a serious problem. I decided to purchase a second licence so that I could use a laptop on the net in addition to my main computer. This is a Dell Inspiron 8100 with Intel Pentium 3 running 866 Mhz. The problem is that after a short time from boot up the whole laptop will freeze completely… the mouse is totally inactive as is the keyboard. I was able to run process explorer on one occasion before this happened and observed that ekrn.exe was using 74% cpu just before it crashed. If the laptop is left alone, after a few minutes it sometimes releases the system and the computer is then usable for a short time again. But really, in essence, the computer is totally useless in this state. Having paid for the extra licence after having no problems with my main computer I obviously am very disappointed with this situation that ESS has given me now. If I remove ESS from the laptop it then once again becomes a very usable computer, but without any net protection I am unable to use it for the purpose that was intended.
