I am having a problem while browsing the internet using Microsoft Internet Explorer 5.50.4522.1800. For some reason, whenever I submit a form (POST method) on certain websites, the active browser, along with any other open IE browsers, simply terminate with no error prompt. For example, if I visit www.barnesandnoble.com, type the name of a book in the search field, and then click search, the browser processes for a few seconds and then just closes itself and any other open browsers. The same thing occurs if I go to amazon.com as well as microsoft.com, so I am sure it is not the web site's problem. I visited Microsoft's Knowledgebase and no one has reported any similar problems with Internet Explorer. If possible, I would like to avoid reinstalling IE. Please offer any suggestions.
