I have tried this workaround it works as described and without a reboot. However it breaks certain applications that use the "Internet Explorer Server Window" most notably Yahoo Instant messanger 5. I does not affect versions 3 or 4. My version of YAIM is 5,0,0,1036. The effect in short the "Internet Explorer Server Window" remains blank not showing the IM texts. This might be due to poor design om yahoos part, but I am posting it as it may effect other applications aswell and might not be a good workaround for all. Best Regards, Per Arne Johansson
