Hi Quentin -
Thanks for moving this to the
forum; I'm sure your post will be helpful to other Mac users who
experience this. I think it's easier to discuss here also.
I
was able to reproduce your problem on my older MacBook, and this is a
MacOS-specific problem that may not have a simple solution.
Double-clicking a .ctxt file launches DeadboltEdit, but the file
information is not getting passed to the application.
I'll
look deeper and do some research. The best way to use DeadboltEdit for
now is to simply launch the app, then use the File -> Open dialog.
If
you decide you would like to go back to the prior version (V3.40),
there is a link to older versions on the website, on the Download page.
I'll update this post when I know more.
