Thanks for the information. I found if I want to view an advanced topic, I can right click and copy the URL into Firefox to prevent IE from launching . I assume the Mac platform will operate the same way and would use Apple's Safari browser. Thanks!

I am running version 6.4.112 on XP and If I select online help from the Help menu, it launches Firefox ok, but if I open the Instructor window and click on any of the Advanced Operation links, it always launches IE to display the links. I have bookmarked the help page in Firefox as a work around and will avoid the Instructor window if there is not a way to make it launch the correct browser.

My default web browser is Firefox and every time I use help in SketchUp it launches IE instead of opening it in Firefox. The help files indicate it should launch in the default browser. Does anyone know how to force SketchUp to use the default browser for Help?
