I've posted this problem before but I've found that it works fine when I go to the webpage on the server (VNC Viewer) but it won't work from my computer. Basically, drop down lists populate each other after a selection is made one by one by using autopostbacks. It seems to work fine on everybody else's machine except mine. It appears to post back but it loses the item that was selected. Any ideas why my machine acts this way? Let me know if any more info is needed. Thanks!
