Double-clicking on a linked block pauses the current instance of Rhino and takes you to the file the block is so you can edit it. This is good, but --unfortunately, when you double click on a layout detail that has a linked block in it – to “activate the detail” – with no intention of editing a block, you are still taken to the external file where the block lives so you can edit it.
It’s happened several time today. I wonder if Rhino could ask you “Do you want to edit this block? Yes/ Cancel” before it actually does it?
