Open/Save As Dialog Box Does Not Appear with NetScape Version 4.x Client Installed

Under the following conditions, Internet Explorer 5.5 Service Pack 2 does not prompt you with the Open/Save As dialog box:

�	You are connecting to a Web server that is infected with the Nimda virus.
�	NetScape Communicator is installed on your client computer.

This problem may occur because of a coding error in Internet Explorer. Because of this error, the Plugin.ocx file would incorrectly run logic to search for a NetScape-style plug-in when an ActiveX control was present to handle the data.
