When you attempt to open another program while you are viewing a Web page using Internet Explorer, one of the following symptoms may occur:
The Web page you are viewing contains a POST command in the Hypertext Markup Language (HTML) document.
Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Internet Explorer caches the data uploaded to the server in random access memory (RAM), filling RAM based on the amount of data sent using the POST command. Quitting Internet Explorer, and thus removing the data from RAM, is the only way to increase the system resources.
