Click the bottom of the remote front panel window or right-click anywhere in the front panel in the browser and select Request Control of the VI from the shortcut menu. If no other client is currently in control, a message appears indicating that you have control of the front panel. If another client is currently controlling the VI, the server queues your request until the other client relinquishes control. Only the user at the server computer can monitor the queue list.
To completely close your connection to the Web Server running on the server computer, click the close glyph on the browser window border. However, if you want to release control of the front panel but maintain a connection so you can view the front panel, right-click anywhere on the front panel and select Release Control of the VI from the shortcut menu.
