Aie!
Have you tried with version 0.23 of the treview module?
I have an ARMX6 with the last version of Rom, this morning I checked against version 1.59 of the toolbox module that there was no problem. The program starts correctly.
There is a window resizing issue that does not exist with version 1.71 of the Toolbox module.
It would be nice if Diderot also worked on a PI4 …. thanks for testing

Have you tried with version 0.23 of the treview module?

I did. I merged !System that was included with 0.15 and it contains 0.23, same error… Also tried RISC OS stable 5.28 and no change…

I will do a test on a Raspberry3 .I’ll keep you informed.

Thank you for the new version , no bugs to report.
