Product : Yahoo Messenger 5.5 (Build 1249)

A vulnerability found in ypager.exe allows a website to inject [malicious] html, scripts, and possibly activex controls into a Yahoo Messenger IM window.

Side Effects:
This exploit has an extremely nasty side effect. If the IFRAME is added to the ymsgr URL in certain ways the IMVironment information will be saved in such a way that Messenger will no longer log in. This requires that either the IMVironment keys in the registry be cleaned or Yahoo Messenger to be completely uninstalled.

Work around:
Until Yahoo can fix the problem the exploit can be avoided by turning off IMVironments in the Yahoo Messenger preferences.

not expecting an answer but it would be nice

I understand things happen that are unforseen. And sometimes these "things" can be very tramatic. I'm not sure if that's the case with Mr. Simpson. However, if that is the case I'll be patient and supress my urge to protest this unusally long wait for an update to you know what. My family members have experienced losses in their life that are unimaginable to most everyday people and it can make day to day tasks and agendas extremely difficult. I'm not asking for a lot of detail. Just a confirmation that my suspicion is tangible. Not sure if you check cnet posts or not but If you read this one I'd appreciate a discreet answer. If you can't due to personal reasons I will understand.. thanks just frustrated with the wait for a word on the dilemna at hand. 17 bucks is a tank of gas. Two cartons worth of cigarette tabacco-papers&filters. a web cam. etc. All those things have functionality which is why we pay for them wether they are good for us or not. maybe he should just open source the darn thing if I'm wrong and he's to busy.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
