That's the first I've heard of a java problem...Your browser crashed with the latest, but doesn't when rolled back a release?
We did have a fairly large number of requests for assistance following the last IQS update, but we generally do get at least a few. I'm surprised, if it's a general java fault, that we don't have far more complaints. As I recall, java is pretty insistent with its update requests, so I would expect java to be updated on, dare I say, most computers - even when other things are not?
I don't doubt, given your experience, that the new java is conflicting with something in your setup, but I'm wondering if it's not something more obscure than the divx webplayer. What version of greasemonkey are you using? I don't recall specifically now, but some people were having major problems with the latest (then - perhaps a month or so ago...) GM release and had to roll back (mine is 0.9.1, with java 1.6.0_24 but I'm on a linux box).
Generally, when people say "browser crash" I immediately go to the proxy settings, but I don't know what effect changing java versions would have there...you can check yours if you want for S&Gs:
Go to Control Panel --> Internet Options --> Connections --> LAN Settings --> UNCHECK "use a proxy server for your LAN". SELECT "automatically detect settings".
Start -> regedit
change the value to 0 using regedit .
so it shows :
If you're absolutely sure of your conclusions, I'm just talking to hear myself speak, but if you think it could possibly be something else, you might also want to troubleshoot by creating a fresh firefox profile (don't let it overwrite your current one) and ensuring (check your addons & plugins) that only the bare minimum is installed to stream on icefilms (including the latest java - and NO antivirus or firewall plugins or extensions [it's a test remember]).
I did a search and didn't find anything suggesting therre is a general problem between divx and java, but it is kind of technical, maybe people just haven't made the connection...
I would appreciate an update on this if you find out anything new (the virus thing, too
