Thanks ondoho, it wasn't so much about the message itself but the fact it was not capturable!

I've tried to makle the point that it is not a good practice to allow messages like that to be transmitted.

I'd like to close the thread but of course, it is not SOLVED!

Can I close it in any other way?

Reminds me of the situation years ago when I found that CUPS was being mandated (despite being a royal pain to set up) as a dependency for darned near everything on the system that might want to print leading me to grumble "OK I know I need A printer service... why does it HAVE to be CUPS? Why can't I use LPRng anymore?"

Q: Why WPS? Is it dependent on LibreOffice? Or vice versa?

Does LibreOffice have trouble reading some old Microsoft documents? Well, I found an old Word 6 file (an old DOS tutorial I wrote for student interns and formatted for an Okidata 192 dot matrix printer) that it read... mostly. I can't say it rendered it perfectly but I was impressed that it read a Word file that, AFAICT, appears to be ~31 years old.

I recently asked the same kind of question.
Other than screen capturing and manually typing the error message, there doesn't seem to be a way.
This is why, in my own programs, I add a "Copy to Clipboard" button.
