If the ZoneAlarm is 'On', while browsing the internet, if dragging the mouse around while browsing the internet or while using other programs on my computer the mouse will 'hang' up and then in two seconds begin moving again. It is frustrating in that it happens about five times while dragging the mouse over the screen from left to right. I know it is ZoneAlarm because if I turn off ZoneAlarm then I do not have this problem. I am guessing that the ZoneAlarm is scanning when the mouse is hanging. Shouldn't the scanning be invisible to me?
Any suggestions as to why this might be happening?
Thank you in advnace for your help.
