Peter,

Does this affect solutions such as the one posted here: http://quality.livecode.com/show_bug.cgi?id=17292 - Comment 6?

I’m curious because I usually modify the revMenuBar stack to add in my own preferred shortcuts, there are also people like Richmond that like to change the tool bar icons etc., so I’m assuming this type of activity will also break code signing validity.

Kind Regards,

Paul
