Hi, I have the following problem with ZSpheres (among a lot of others with these tricky little devils :evil: ):
When I have made a construction of connected Spheres and switch to the move-mode and then click on a ZSphere to move it in the Construction on the canvas, the whole construction oftly disappears suddenly.
When I redraw it then on the canvas again, it can only be scaled to an specific point (the construction stops scaling at a very small size) and finito.
Storing and reopening the file gives me the construction back again with normal behavior, but after a few minutes (Move-mode and clicking on ZSphere) the same occurs again.
Any ideas ?
