I only use it if someone posts they'll be a meeting there.
I found that using Internet Explorer causes lots of problems with flash. It would never let me use it and was always telling me there was an error or I hadn't installed the flash plug in ( or whatever it is lol ) when I had. I switched to Firefox and haven't had an issue since, so if you can't use it try firefox....I've never looked back
I'm not advertising btw, just advising on past experience
