Java version: 6u20
Operating System: Windows Vista
Browser: Firefox3

I uninstalled 6u18 yesterday on my Vista and then installed 6u20. After the installation is done, it prompted with a dialog box to restart the machine for 6u20 changes to be effective.

But I forced it not to restart by clicking "No" in the dialog box. Everything worked fine ( Teamsite launchpad worked fine ).

Last night I had to shutdown my machine and this morning ( after the restart ) when I logged in to TeamSite I see that my browser is being crashed when i try to edit/view a file in TeamSite Launchpad ( Teamsite launchpad uses JRE )

Here are the steps to reproduce :

#1 On Vista, install 6u20 ( having 6u18 as previous version ) and restart the machine
#2 Go to Teamsite - http://star-auth1.sfbay.sun.com/iw-cc/command/iw.ui
#3 Browse to the directory - //star-auth1/default/main/www.java.com/web_site/en/static/WORKAREA/draft/en/download
#4 Select any file and do Actions --> View Source
#5 Browser is crashed.
