The UI for Python window in grasshopper could stop working for no reason


not the first time i encounter this.

I cannot click anything and there was an offset with the clicking inside the window.

Could you please send the gh file? Only then can we possibly find a solution.

I don’t think it has to do with gh file. I have similar experience with other gh files.

the python window is unstable in multiple screen set up with different screen-scaling.

I suspect this is an eto issue

Thanks for the video. I’ve assigned this to Ehsan but like you said might be a Eto issue related to multiple monitors. Can you run SystemInfo and post the results? Thanks
