Dug some more info, when I "Inspect" a weapon in Chrome I see this: <span style="color:inherit;font-size:inherit;" title="Att:307 Def:429">1 Radiator</span> So it's not "Javascript" - it the use of the html title attribute not showing as tooltip in Chrome.
It almost seems random - some people it works - some it doesn't - on code.google.com there are lots of issues with tooltips/title not working.
I'm in IT, so to me it's important to understand why this seems to affect some people and not others.
something i'm sure will be fixed momentarily. i didn't even know this was available to us until i saw this thread. anything that does not appeal to the majority of the player base will surely be given to us in short order.
It works in IE, but I didn't realize that until just recently, either. This must be one of those updates that the player base was clamoring for a couple of years ago that I missed.
