Steps for recreating the bug:
Make a box and a plane that goes through the box.
Start the CreateSolid Command.
Select box and plane.
Now change the CommandLine option from yes to no or the other way around (happens in both cases).
The box and plane automatically get deselected and there’s no way to select the objects again. It seems like the objects are locked whereas I would expect them to still have a selected preview (= Yellow).
That being said, when I press enter it does seem like the command remembered the objects and completes fine. I just didn’t get any feedback saying those things were still selected.
