Problem MenuButton mouse event exception

[ipindado]

Hi Isomorphic...

I've found a strange exception in a configuration with a MenuButton and a large number of MenuItems when the scroll bar is displayed. The exception happens on mouse events around the v scroll bar.

Thanks and Best regards...

Version: "SNAPSHOT_v10.1d_2014-11-12/LGPL Deployment"

Browser: Same exception in IE11, FF 33.1.1, CHROME 39.0.2171.71 m
