Repeat Entries Into Meetings

[djl1]

Since I upgraded my account a couple months ago, I seem to always need to repeat entering into meetings. This includes meetings I've scheduled, as well as meetings I'm joining. I go in, find it not working (freezing image), and leaving, then re-entering. I get the message that it isn't responding and do I want to close the program. I close it and re-enter. Second entry works. 

Is anyone having a similar problem?
