Introduction

In certain situations the pythonnet interface does not release a used Python lock. This can cause a deadlock situation in AutomationDesk, since AutomationDesk will not continue as long as the lock is present.

dSPACE has created a hotfix for the pythonnet module of  the delivered Python 2.7 64 Bit and Python 3.6  64 Bit distributions, so that this problem no longer occurs.
