I don’t know if anyone else has this problem, but every once in awhile when I am building a model with zspheres the model will suddenly shrink to a tiny version of itself. Then, if you try to scale the model up, it will only scale up a little bit, and it is impossible to work with.
The workaround I found to this problem is to turn off edit, redraw the model on the canvas and delete the tiny one. Sometimes you will have to hit undo a couple of times before you redraw the model, or it will redraw it at the tiny size.
