We recently updated to the newest version 2015.2.729.40 and our Rotator image onclick doesn't work in Chrome and doesn't work on some machines in IE.
We had <asp:Image controls in our rotator which are rendered as <mg
To correct this, we had to change the control type to <asp:ImageButton which renders as <input
Again, this issue only happened after our recent updated to version 2015.2.729.40
