I have deleted all photos from the circuit diagram. I had the photos in the plan for a more detailed explanation.
Since the photos have been deleted from the circuit diagram, I have not had the error again.
Thank you very much for the effort and help, I can work very well with the program
Many thanks

I have also tried version 0.100 DEV on my Mac. It also looks as if the program hangs briefly at the lines
15:30:56.426 Debug: Export XML de 30 schemas (sources/qetproject.cpp:954, QDomDocument QETProject::toXml())
15:30:56.427 Debug: "exporting diagram \"cover sheet\"" [ Diagram(0x128e0b5a0) ] (sources/qetproject.cpp:959, QDomDocument QETProject::toXml())
15:30:56.459 Debug: "exporting diagram \"Feed\"" [ Diagram(0x1153ebbd0) ] (sources/qetproject.cpp:959, QDomDocument QETProject::toXml())
Perhaps especially with the line
15:30:56.426 Debug: Export XML de 30 schemas (sources/qetproject.cpp:954, QDomDocument QETProject::toXml())
I will continue to monitor it
could be exactly like the Windows version

I have tried version 0.100 (DEV). Attached is the log file. In the section "exporting diagram \"MDT Sc...."
I had a program hang. I cannot say what the program is doing there.
I still have to test the CAD program version 0.100 on my Mac

Yes
I will try that out too

Yes, I have tried another computer. On my MacBook 13” M1 16GB Ram
the program behaved exactly the same as on the Windows computer
I will try the 0.100-devel version and watch the logfile
Thanks for the hint

The program hangs cyclically every 8-15 minutes for 1-2 minutes

I have already switched off autosaving. On the PC I have set the energy options
set to Max.
I have also tried older versions, always the same.

It is not possible to work properly with this program

Das Programm hängt sich bei mir zyklisch alle 8-15 Min für 1-2 Min auf

Habe das Autosaving schon abgeschaltet. Am PC habe ich die Energie-Optionen
auf Max gestellt.
Habe auch ältere Versionen ausprobiert immer das gleiche.

Ein vernünftiges arbeiten ist so mit dem Programm nicht möglich
