The site (any of them) some times hangs when I am trying to post something (a question, an answer, a comment, or even a vote). Some times it also slows down the entire computer. The connection appears to have been lost and I am forced to open a new tab or restart the browser.
I am not experiencing these symptoms on other sites, nor on Chrome or Firefox. Has anyone had this problem? I am using Opera 10.6 (Build 6386) on Ubuntu 10.04.
