I joined an on-line social forum and for some reason I am unable to post any messages, or reply to any posts. When I attempt to do either one, I received an error message from Internet Explorer which says it has encountered a problem and must close. It only closes that forum's window, all other windows using IE are up and running. I belong to numerous other on-line forum and have no problems in posting. The site recognizes me and I am able to read all postings; and I am able to use the forum’s personal message program. Using the PM program, I explained my problem to the site administrator……..this is her response: “I understand now, but I'm not sure I can help. It may be a security setting, but I also fear it may be malware. I might start with lowering your security (if you're comfortable) and a virus scan” I have no virus, at least not one that Norton product can detect, my security setting is set at a medium setting. I do not use any other browser. And, as I said earlier, I am able to post on all other forums. I would appreciate any help you can provide me. Thanks.
