Dear list,

investigating the issue of why Acrobat Reader DC doesn’t recognize
ConTeXt signatures, I related it to another issue.

I use Acrobat Reader DC for Windows at work. DC is regularly updated.

Since a year ago or so, if I open a PDF document (opening Acrobat with
the document) and double-click (sometimes, it may be triple-click) too
fast on a link or a signature field (either to be signed or already
signed), Acrobat Reader crashes.

I have tested sample documents on other computers and with other people
and everybody told me Reader crashed.

BTW, the document structure is perfectly fine (according to the
Arlington PDF model from the PDF specification).

I thought Acrobat Reader DC changed something and this was buggy. I have
been consistently experiencing this issue for about a year, so I took
for granted it was a common bug.

I experienced the crash only with the Spanish version (the one installed
on all tested computers). Although I sometimes I load the English
version by pressing Ctrl when starting Acrobat, right now I cannot say
whether I experienced the crash with the English version loaded.

But this seemed to be not enough, since I have just found out that
Acrobat Reader for Windows and macOS with the US English version may not
crash (I was told).

The sample document contains only a link. It has generated from the
following source:

  \setupinteraction[state=start]
  \starttext
  \startTEXpage[offset=1dk]
    \protected\define[1]\myurl%
      {{\tt\goto{\hyphenatedurl{#1}}[url(#1)]}}
  \myurl{https://contextgarden.net}
  \stopTEXpage
  \stoptext

Sorry for asking for this, but would you be so kind to compile (or
download the attachment) and open it with an updated Acrobat (opening
Acrobat with the document)?

I need that you double (or triple) click on the link (to the Garden) as
fast as you can.

Either if this crashes Acrobat or not, I would really appreciate if you
could tell me which is your OS and language version of Acrobat.

I’m affraid I cannot tell yet what may be triggering the crash, but I
view PDF in Windows with SumatraPDF.

When I open them with Acrobat and click on any kind of link too fast, I
get back to SumatraPDF (since Acrobat crashed and dissapeared).

Excuse for what it seems to be a tricky issue with Acrobat (the
signature being way more important than the crash 😅).

Many thanks for your help in advance,

Pablo
