the past few days when i use i.e. i get an error message saying explorer needs to close. it seems to always happen if there is a popup on whatever page i am looking at, but sometimes there doesn't appear to be a popup when this happens. when explorer shuts down it removes all the icons and the taskbar and i have no choice but to restart the pc. it happens within 5 minutes of using the net and i need help. sorry that theres not much to go on but does anyone have any ideas?
