Vensim PLE MAC v8 unstable on student machine.

Post by eliotrich » Thu Feb 13, 2020 6:13 pm

Hello.

I'm fielding a student problem, after his installing last week:

"I am really struggling with the VenSIM 8 program on Mac. The program keeps shutting down and SOMETIMES it will save my data, and at other times it will not and completely omit all of the graphs and charts."

It's intermittent, so we have no screen shots. Models are small and work fine on PC.

Any suggestions? Is V7 more stable?

regards,

Eliot

What is the exact version they are using? 8.0.9 is available now which has many bug fixes.

Also, what are they doing when it crashes? Is it a certain model? If yes, can you upload it so we can try and recreate the crash? If we can recreate it, we can fix it and possibly provide a workaround.

Also might help to know the OS version and anything unusual about the machine.

I and my students are also having similar issues. I am personally running 8.0.9 PLE on a MacBook Pro using the latest version of Catalina. The crashes happen in a number of models and at various times. Hard to see any real pattern yet.

One other quirk. When I am using my machine with additional screens, e.g. a wall projector, the main window will sometimes just disappear. It looks a bit like it has run off to another screen somewhere and the software doesn't really crash. To get the window back, i just click on the Vensim icon in my Dock. Sometimes it does this several times in a row when I am trying to select a variable to modify when I am using SyntheSim or SimSetup. It is almost like a game of cat and mouse.

Hi.

8.0.9 PLE
MacOD Cataline 10.15.3
MacBook Pro 15", 2017
16Gb

Problems occur from vensim start,
I've just tried this on a Mac (not Catalina, I cannot really "upgrade" as I would not be able to run older versions of Vensim). A general session of running the model, using the tools etc, I had no issues.

Is there something that reliably causes a crash?

Nothing reliable, sorry.
