screen share

[MBB2144]

I was attempting to share my screen yesterday and it would get stuck on the same screen, even after I stopped sharing and reshared.  Did it 6 times and would stay on the same screen for my client.  On my screen it was saying it was sharing the new screen.

I thought there was something wrong with my system, so I did a practice run with 3 other participants today and it worked fine.  This made me think there was something wrong with my client's system from yesterday.  Has anyone had this problem and what did they do to fix it?
