I just installed 20 Windows XP Profesional in our compnay work station. Users keep complaining their Windows Explorer left hand pane keep refreshing/flickering when they click on the plus sign of the folder list in any of the mapped network drive and have leave it open for several second. It's only happen on windows xp pro client's station, Windows 2000 and 98 do not have this problem. Did any one have the same problem? I couldn't find the reason why it did that. Any info would be apreciated. Thanks..
