MS_PDF_PRINTER is defined as "Microsoft Print to PDF"

Have you an idea, what can cause this error (only sometimes) ?

This has always been a conundrum for me.

It makes no sense that there is something wrong with the code, because it is a rare occurrence.

I'm going to try to do what Microsoft does and break past the error to allow the user to try again at a lower level.

OOPS. Something went wrong. Please try again.

This requires that you, the programmer, be familiar with BEGIN SEQUENCE and END SEQUENCE structures so a Break() will work properly.

Thanks, Roger.

Here is an updated _DCFONT.PRG (renamed as _DCFONT.TXT) with an error trap.

http://bb.donnay-software.com/subscribe/_dcfont.txt

Copy it to your \exp20\source\dclipx folder, rename it to _DCFONT.PRG and run build20.bat to rebuild dclipx.dll
If this error occurs again your user should see a message box (OOPS. Something went wrong. please try again), and a BREAK will be sent to the most recent END SEQUENCE in your program.
