I name all of the objects I model in the Properties: Objects panel using the Name field. Makes life easier when importing the finished model into my rendering software. Rhino crashes every time I use a keyboard shortcut after having changed the name of an object, but only before clicking out of the text field. Basically, isn’t that Rhino crashes because I’ve renamed something; it crashes because the text in that field is either highlighted or has a blinking text cursor in it.
As an example, if I selected a number of identical objects, rename them, press enter to commit the name, then use Command-G to group them while forgetting to click elsewhere to remove focus from the text field, Rhino will crash. Every time.
It did this in Rhino 6 and still does this in Rhino 7.
