Hello everyone,

Before I open a ticket with Siemens support, I was hoping someone here has encountered this problem and managed to fix it.

I have just switched to a new laptop and installed Step 7 5.7 SP2 HF1. The laptop is running Windows 11 Pro 23H2 and I have been testing everything to see if all works.

But I just ran into the first problem, when I compare the project blocks with the online blocks, I cannot select anything in the compare blocks-results window. Every time I click on something in the window, the block turns blue just for an instant and then is immediately deselected and the compare blocks-results window is deselected also. Even if I just click anywhere inside the window, the window complete window is deselected immediately as if there was a higher window open but that is not the case. 

I am running two monitors and this problem seems to only happen on the monitor that is not declared as my main screen in windows. When I compare blocks on the main monitor, it works as it should. Has anyone encountered this problem?

Thanks 

Hi, I am encountering exactly the same problem running Step7 V5.7 SP1 on Win11 Pro 24H2.

Does anyone find a fix for it so far?

I have same problem too!

as you said, i can work with another monitor.

thanks for your solution.

Siemens need to fix it
