TronPrint crashes wz4CE on showing this operator.

I don't know what this operator is supposed to do.

If you put a bitmap in doesn't crash but disaply a big cube.... any idea ?

Ahhh. I see. Stack a TronFont bitmap to TronPrint input and it will work OK!
I think no operator should cause wz to crash even if used in the wrong way.
Is there anything you can do about the crash?

it looks like this operator only work with bitmaps so I can force it to have at least one bitmap op on entry else "missing entry" error msg.

done

in fact to use it correctly you need a tronfont bitmap operator.

Yep. It should behave like any other op requiring something on input i.e. disable 3d view, become red and show "Error: required input is missing" in the info line.

Yes. Exactly! Fixed! Great many thanks.
