This does not have any information behind the post.
Are you saying you have set up several web cam's for clients on your business catalyst sites?
If not you have posted on Adobe forums in their Business Catalyst system web apps section, Adobe do not make a browser if that is what you are refering too. If you are talking about Adobe Flash that would be a different section of the forums.
In either case - Check your flash installation, check that you have not got a browser ad block plugin running.
