No, I don't use VB at all. In the vast majority of cases I've observed so far crashes took place while was working in browser (cwww/chromium). One more thing (well... I know it sounds a bit odd... but still): it never crashed during surfing heavy pages or audio/video playback but on submitting simple text messages (issue tracking system, code review tool, wiki and so forth). -- WBR, Andrey Kosachenko
