I noticed that FogBugz uses jQuery version 1.3.2 (according to $.fn.jquery). That version is almost three years old.
Since recently, my up-to-date Chrome logs this warning in the console many many times:
event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future.
This is supposed to be fixed in jQuery 1.7.
I also noticed some bugs in the 1.3.2 version while trying a BugMonkey customization.
I'm sure upgrading to a recent stable jQuery version has all kinds of advantages. Can we have it in FogBugz, please?
