I think the only change was an upgrade to IE9 after my hard drive crashed and was fixed by IT professionals. They installed IE 9 rather than IE 8 I was using and now the Sweet IM extra for Messenger no longer shows at all.
...found works on a mac ok; and when does not work that am running windows 7 with IE9 on my windows based computer...
When attempting to send or reply to an email in hotmail, using IE9 the Internet Explorer Security pops up and my comuter locks up.  I have to use task manager to unlock it.  I do not have this problem with Chrome,  This seems to happen after an update but then it works ok after another.  What going on?
