Modeller causes SMath crashes w/o dialog if a template contains:
- wrong templates (i.e directly the polygon)
- imaginary numbers
- if you delete or disable the polygon (in the 2nd attachment, use the "OK" variable, enable the template and then delete/disable the "OK" variable)
the attachment "modeller_updated" contains small examples; change the template variable and then enable the template from the context menu of the region.
(please delete modeller.sm)
