Get ResizePoints in studyOverlays to work

[moti]

I can not get resizePoints to work in a StudyOverlay (plot below the price graph). When I set the indicator to show up in the Price Graph it works as expected (in the Option Dialog of the indicator set Graph to "Price Graph"). When the indicator is in the default location (plot below PriceGraph), then when selecting the ResizePoint it will be highlighted, when dragging it the charts moves instead of the resizePoint.

Any clue how to solve this ? Or do resizePoints only work properly in tyhe PriceGraph ?
