Well to be clear, I stated 'experienced' users, which does not of necessity include advanced users. An aquaintance of mine has not-very-many years of experience, but is in all regards a much more 'advanced' user than 99% of the people running CAD or being CAD Managers.
As to why I think it's the correct answer to your issue? It works. It's easy. and an experienced person wanting to get his job done competently should always use a method that works.
Double clicking has always had, and always will have, issues when you have more than one version of AutoCAD installed. That situation breaks the one-to-one correspondence that Microsoft built into the double-click mechanism, and is compunded in Acad since the Acad.exe for various verticals is the same file and the various verticals are loaded as options. Euqally applies if there are multiple .dwg file handlers, Carlosn, Draftsight, TrueView, etc. How can MS pick correctly which you want to use at that particlar moment?
Re-reading your original posts, I may be misunderstanding your issue. to quote Pendean...
