There are several ways of creating new viewers (project viewers and bugzilla viewers):
To remove a viewer use the menu: File > Close
Note: Selecting File > Exit will exit LiveProject, closing all viewers. All viewers will be restored when LiveProject is started next time.
Note: Clicking the X icon in the top-right corner of the viewer window will only minimize the viewer. Minimized viewers can quickly be re-shown by double clicking on the LiveProject System Tray icon.
In older versions of LiveProject, viewers started out as separate windows (And back then they were called monitors). From version 2.0 and forward, new viewers are created in tabs in the Main Window. It is still possible to Detach and Attach viewers.
