#34 incorrect treatment of transitions

[Felix]

Hi there,

appreciation for the initiative and a great work.

Unfortunately, there are some disturbing bugs in the program.

wrong transition handling:
- In some situations, transitions do not remove the tokens from the incoming circles.
- In some situations, transitions are not active even though they should (prerequirements are met).

I attached a model for mutex. Unfortunately does it not remove the central resource in all cases, so that mutex is not realized.

Cheers,

Felix

Fixed in version 4.1. This appears to be a result of places and transitions not properly being deleted during a save. There are duplicated arcs in the model that was attached.
