SVG widget and grab me command

[hh]

Widgets are not ordinary controls.
So this is not a bug, rather a missing feature (the widget
author will have to implement an own "grab"-handler).
The widget passes mouseDown but not in a way that "grab" can
be used. MouseMove isn't passed (=> not usable) at all.

You could try "ControlHandles89" from "Sample Stacks" or
http://livecodeshare.runrev.com/stack/902/
which adds handles to widgets for resizing and grabbing.
(Or use a solution similar to that).
