Simulation stops for some reasons on random frames

[caypiranha]

Unfortunately - autosave is set off.... Otherwise, it might be a promising hint! But I´ll check it on the other machine with brand new Installation and there this may be still ON.
So, one Machine, there maybe is Ram really the issue and on the other is the Autosave set ON and might stop for this reason ... well confusing. I´ll check this later.
