Thanks, smitee, for the kind response. Please note that there is no problem when I first start IExplorer. When I Ctrl+Alt+Del on this page , I saw exactltly as you wrote "Problems with IExplorer 6!- Tek-Tips - Microsoft Internet Explorer" . The trouble begins when I close the browser ! On the screen, IExplorer closes O.K. but when I
Ctrl+Alt+Del , I see "Iexplorer" there ( and of course "explorer" ). I can not <end task> "Iexplore" : it just stays there ! Then the system hangs! To continue, I have to restart the system. So the problem starts after the first closure of IExplorer in a session !
My theory is this : when I reverted back to IExplorer v5.5, some .dll files from v6.0 were left unchanged and not over-written ( i.e. may be due to a more recent date stamp ?? ). The mixed bag of .dll files from different versions could cause this problem.. I shudder each time thinking of the final solution : reformatting the HD ! I would rather wait for more suggestions than doing the reformating...
