Now that the settings have been modified for your particular computer, the Xpression virtual environment is ready to start. Select the Xpression item from the main window, then the start button in the upper-left corner. This will open a new window, which may be black for a while, or flash text, but this is normal. If any pop-up windows occur, select okay, since these are likely asking you to use the mouse cursor within this window as if it were a computer itself.
