I was able to install today's build just fine, using the custom install - no crashes.. I'm using it now to post here.
oops, I meant the stub install, using the "Custom" option to install just the browser, mail, and AIM.. I also don't set netscape.com as my homepage, nor use quicklaunch (if any of those variables help..)
arghhhh....looking forward to the refresh here. My Windows machine has become intolerably glitchy. I rebooted the machine and tried to install this build and it worked fine. Doing smoketests now. marking invalid....
