This is all dependent upon which version of Navigator your have; however, here are the three ways to disable it. One of the below methods will disable Navigator from automatically loading.

1.) Ensure that it is not in the startup folder; you can check this by clicking on start / programs / startup. If you do not see Navigator listed under startup, skip to #2. If you do see Navigator, click start / settings / taskbar / click the tab start menu programs / advanced / click the folder that says programs / then click the folder that says startup; highlight navigator and press del on your keyboard, say yes and that should resolve the issue.

2.) If Navigator was not in the startup folder then click start / run / type in win.ini / look for a run= line, usually the 2,3,4 line, see if there is a statement saying C:\NAV\NAV.EXE   If you do not see this, skip to step #3; if you see this, delete just the C:\NAV\NAV.EXE and this should eliminate Navigator from loading up at startup. If it does not, you may want to edit the win.ini by following the steps above and put a ; (semicolon) in front of RUN=   this will remark the line and should make Navigator not load up at startup.

3.) Usually, if the first two were not able to stop Navigator from loading, you will have one of the newest versions such as 3.9. To disable this, you will need to click on start / run / type in system.ini search for startnav.dll or something similar; it should be related to nav and usually will be on the drivers= line in the [boot] section.
