No matter using my laptop with xp/ie6 or my desktop with win7/ie8, the latest release 2010 build 123 rarely crashes even I keep my system and browser running for 3+ days due to working requirement. If you ever used Chrome, you'll understand what these ybrowser.exe are for. I choose it instead of Chrome due to its stablity and compatibility.
THANKS A LOT
