Recently I thought I had a Yahoo Messenger issue conquered. The computer I was working on had an issue where typing on Yahoo Messenger when you hit send it would disappear, but the recipient would see it, but when they sent an answer back it could not be seen either. But when the user went on Yahoo Messenger the next day, it would work perfectly. Then the next day the messages would disappear. Similar thing is happening with Yahoo email. I checked for Malware, nothing. I uninstalled and re-installed Yahoo applications, no change. I disabled Yahoo add-ins on IE, still the issue keeps happening. Running Windows 7 32 bit. Any ideas??
