I needed to do a quick screen-sharing session with a couple of folks today.
In the past, I've always reached for MSN Messenger. At my last client, Messenger was the default chat client, and since it has built-in application sharing, we used it daily for all kinds of tasks from troubleshooting code to figuring out where to eat.
For some reason, however, I got stuck in an infinite loop when I tried to use Messenger to share a web page. Selecting "Application Sharing" from the "Start an Activity" menu, I was presented with this disturbing message:
Your invitation was not sent because you need the latest version of Messenger to use the Application Sharing feature. Please go to the Windows Live Messenger update site to install the latest version.
