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

Stephen Barncard via use-livecode
Hi,

maybe this is of use for the one or the other.
in any case LC crashes on Mac to desktop when opening a PDF in the Browser Widget and your are getting crazy because of that,  then check if Acrobat software is installed on your system.

A few days ago i mentionend in an answer to an other post, that   LC 9.5/9.6 and also standalones created with that versions, but not LC8, crash to desktop when one opens a PDF in the Browser Widget.

I contacted support, as i was pretty sure that this worked in the past.

As this only happened on my iMac, but not on my Macbook, i decided to completely erase the hard disk of my iMac and reinstall the OS and all needed LC stuff, because i had to finish some important work and waiting for an answer from support or continuing on the Macbook was not an option for me.

I planned to install the other software one after the other  when i needed it.

All went well and the problem with the PDF in the widget did not happen anymore. Today i needed to install Acrobat DC for some tasks.
An hour later or so i received an answer from support and one question from Dev team was if by any chance Acrobat software is/was installed on my machine.

I tried again in LC and the crash happened again. After uninstalling Acrobat DC the crashes did not happen anymore.

I reported this back to support.

Of course not using Acrobat DC anymore is no final solution, but for the moment it´s a workaround and hopefully the Dev team finds out what exactly is going wrong with.

Matthias

Well, we confirmed it crashed ;) Whether it is a bug in LC or Adobe DC
or not
is another matter.

There was a similar issue a very long time ago with Adobe's PDF plugin -
it would
cause the browser external to crash if used (we used the system webview
back then
as we do now)... The Adobe plugin was doing things it shouldn't (I can't
recall
if we managed to come up with a hack in the browser external to stop it
or not; or
whether Adobe eventually cleaned up their plugin!)

Warmest Regards,

Mark.

Yes, you are right. I am sorry.
I should have written that LC Dev Team confirmed that there is a incompatibility between LC 9 and Adobe Acrobt.
But at least, it´s confirmed. ;)

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
further.
