Very sad new for me, that you will retire the old gui. i tried t use the new gui. Building a model with the new gui, triple my building time.
I will try to keep the present version as long as possible.

Re: impossible to switch back to the old gui a model built with the new guide
Fortunately this is the only model that cannot be switched to the old guy and cannot be loaded when the old gui is on. All the models work correctly. I suppose that something happened when building the model with the new gui on. Anyhow finding the old gui much more practical, i wolk now only with th...

Re: impossible to switch back to the old gui a model built with the new guide
If I open your model in the download repository, it works fine and I can switch tp the old gui, but if i download the model joined, it generates again an error if Venim is set in the old gui. I am obliged to set Vensim in the new guide, to be able to load the model, And once loaded in the new gui, i...

impossible to switch back to the old gui a model built with the new guide
Hi Joined a simplistic model that when loaded from the vensim set with the new gui, loads correctly, but once loaded it is impossible to switch to the old gui. If Vensim is open with the old gui set, it is impossible to load the same model. it opens it on the second view, and if one wants to go to t...

Hi.
Thank you for your answer.
There is no run option in the file menu in the Vensim text editor. I tried too the new text editor of the menu. It has no run either.

Do you mean that just by translating my simple model to Stella, without anything else, no server, no hosting, anybody with a web browser can use my model and be at the same time guided the same way that Venapp can guide an end user or course with a minimum of coding? Is it worth moving to...

Re: Units Check whack-a-mole
Hi
It might be better to use the strict unit testing. If you use the strict unit testing two more errors will appear in both models. But I do not think that these errors have anything to do with your problem.
