If you cannot advance to another page in the white board, someone in your meeting has it locked. You will need to have them unlock it with the Lock Contents button on the tool palette. Sharing Applications One of the most powerful features of NetMeeting is application sharing. Sharing actually is invoked in two stages, application sharing and application collaboration. Sharing gives your students or peers the ability to see the application running on your machine, but they cannot affect the application in any way.
Collaboration gives users the use of application features.
Not only can meeting members see the applications, they can participate in their use. Sharing is useful for demonstrations or walkthroughs and collaboration is used for jointly working on a document in the application that has been shared. Effectively using the collaboration feature requires the use of some sort of protocol to enable users to decide whose turn it is to speak. In application collaboration however, we speak by using the mouse and keyboard. Any Windows application and the program only needs to be installed on one machine.
