i have read alot of questions about ie 5.5 & 6 being slow or jerky. i myself had the same problem which is why i subscribed to this forum. i have found a solution to my problem so it may work for you: i have diskeeper professional installed on my IE 6 win xp home. go to "change your settings" in diskeeper.
then go to set performance date options. click on it. Uncheck "allow collection of performance data" then click ok. thats it! oyur done.
i believe the reason why my explorer window was jerky is because when diskeeper is collecting the performance data, that is when my explorer window freezes for a second. hope this resolver your issue and have a nice day:lol:
