Every time I released the left mouse
button, the widget interaction
component would stop following the
mouse and would stay focused on the
area I released the mouse button over.
Ah, that’s pretty cool actually (in a bad way). But I learnt something.
Disabling the functions codes for
getting the grab offset and mouse move
position fixed this issue. It seems
the code isnt compatible when using
the widget interaction component. What
could be the alternative to this ?
So we’d need an offset from where the interaction component traces against the quad of the widget component and translate this into a 2d offset? Ha, this is going to be neither pretty or easy.
Nothing comes to mind atm; would have to grab a cuppa on a Saturday morning for this. On top of that, I’ve worked with the interaction comp just a few times, and never with anything serious. 
Pretty sure it has quirks of its own, too.
How jarring would it be if you got rid of the offset and held the widget by its centre only?
