1.7.4 hidden propertyes

1.7.4
Looks like problem with hinge spawner caused by new behavior of script engine.

There was a good trick to read hidden variables (like geomID)
1) set geomId to some value
2) draw something (or set restore point in script)
3) undo
4) look into script window and you can see real value instead of some you set (or use it in script)

But that value you set never affect Scene.AddHinge/Fixjoint function till now.
