A real-time collaboration client and a method of configuring the client for a real-time collaboration with requiring the client to be rebooted. A secondary table of display driver calls is patched to call a redirection table instead, while the primary table is unaltered. Redirected calls are passed to the display driver and to a collaboration module configured to update the collaboration to reflect the display driver call. The video mode of a client video display is then changed, at which time the secondary table is copied over the primary table and made active. If the client is rebooted, a loader module loads before the display driver and intercepts a call to load the display driver. The loader module loads the collaboration module and modifies a return value to the call to cause display driver calls to be directed to the redirection table.
