This article describes how to display Dameware in full screen mode.
All DameWare Mini Remote Control versions
The DameWare Mini Remote Control program resizes the application window to the same resolution as the remote machine's desktop.
The only way that the DMRC will run full screen and take up all of the screen is, if the local and remote displays are set to the same resolution.
If you are running the same resolution on both, then click the DMRC full screen tool bar button to enter full screen mode.
