FYI: Cause found for LC crashing to desktop when Browser widget opens PDF

I believe 32bit run mode was the default for earlier versions of LiveCode
but 9.x is 64bit by default. I bring that up out of curiosity because I had
a problem with a browser plug-in (64/32bit) running inside a LiveCode
Browser widget in the past. The plugin would crash running in 64bit,
sometimes taking LiveCode Engine with it, but if it worked perfectly in LC
in 32bit mode or earlier versions of LiveCode.  Of course the plugin worked
fine in Safari and on both 32bit and 64bit kernel machines. I've since
replaced that plug-in with my own LCB Library that does most of what I need
that fo (and also got rid of my 32bit laptop) so I didn't investigate
