But that was exactly what we said you had suggested earlier and when we 
tried that it didnÂŽt work. The other constraints worked just fine, but 
not this one. Do you have any other ideás?

Unfortunately we couldn't test this because if we use the constraint above 
weÂŽre not able to draw any transition from any state. Something goes 
terribly wrong.

Yes. We tried that. As we said in the previous post. It only makes the 
object non resizable when it is already drawn.
We would like to have a fixed size from the beginning, the person using 
the editor should NOT be able to choose how big the initalState is but it 
will be, say 15*15 pixels all the time. No bigger no smaller ever. Can 
this be done?
