When loading data from an attribute in TaurusArrayEditor a dialog is shown asking user to proceed, but this dialog only shows "Accept" option and furthermore if you close the dialog using the window close X (at least in KDE) the answer is assumed to be yes.
I propose the attached patch as a solution.
I could reproduce the bug and reviewed the patch, and I'm agree to apply it.
The patch has been applied in Taurus 3.7.2. It is still pending do it in develop (Taurus 4).
Thanks,
Carlos
