HI,
I have done what you recommenced, and it doesn't work either,
in fact i tested the demo project (WebGMapsDemo.dproj) and it does not
work on IOS and MAC, the event only works on Window.
The On MapClick, OnMarkerDragEnd, OnMarkerDrag,OnMarkerDragStart.
I just updated the compos to 2.6 Version.
Hope we get a fix
Thanks
