I have the same problem I already had in Rhino5, that sometimes Grasshopper doesnt reacts to my keyboard for exapmle when I try to delete a component by hitting delete.
I still can delete over the menu, also when I double click on the canvas I can write, just delete, alt+,ctrl+c.ctrl+v, etc doesnt work.
In rhino5 I unloaded GH in this ocassions, and everything was fine, most of the time.
Now I close rhino, since GrasshopperUnloadPlugIn doesnt exists.
Do you have an idea about what steps may lead up to this situation? I realise it’s probably not 100% repeatable, but any hints may be useful.
The attached user object will unload all documents and close the window (it won’t work if any other documents are unsaved, but if you drop it into an unsaved document, you will lose changes). It’s clearly a hack, but if it alleviates the pain…
Not sure if this is helpful, when I lose keyboard focus for GH in R5, I can get it back by double click on the header of GH window to minimize and maximize the window again (sometimes I do it several times just to be safe), usually that will get it back for me, (learned that from someone on the GH forum, forgot who and where the original post is), I didn’t have to unload and reload GH.
I don’t have R6 yet and can’t test this if it’s still viable.
