SIDE 1239. NOT SOLVE MATRIX

This simple circuit, to 5v normally ok, to 9v or voltage greater than 5v produces "Not solve Matrix". Tell me please. This version and W11.

It is working for me in Linux and Windows.
Is there any sequence of actions required to trigger the error?

When it works ok, all de probes works, it is easy to see when fails, also appers de red baner. I will prepare for you more info.

Changing to 9v it fails always.

In w11, make a folder, copy there the zip file, unzip, run it. change to 9v, it fails sure. When run ok, typically at 5v, the probes change to orange.

Sometimes if it has worked at 5v, it works at 9v too, but it is not consistent. That is why creating a new folder without running it at 5v typically fails at 9v, also at 6v, and so on. higher than 5v.

Thanks, now I could reproduce the issue (in Windows).
It always happen so this is a perfect case to solve the issue.

Then... "Suerte, vista y al toro"

It was a problem with zener diode.

Solved at Rev 1265.
