I've been using Google Chrome since the first day it was available for download and has made it my primary browser at home. It's been causing me some grief when I tried to upload files in gmail for sometime (nothing gets uploaded) and I have opened a case with Google.
My bug report was then merged into another one related to "Flash". Since then, I learned that it's the Adobe Flash Plug-in that's causing the problem. There are several threads, that are still going on for about a month now and it is not clear whether the issue is yet finally fixed.
In a similar case, after I upgraded several Macs to OS X 10.6.7 and installing Firefox 4, people started to complain. Upon investigation, we found out that Flash plug-in was the culprit and disabling it would fix freezes.
