Summary: Open Object Rexx Interface Error - RxWinExec

Initial Comment:
Occasionally, will encounter an "Open Object Rexx Interface has encountered a problem and needs to close" error.  The error occurs when calling RxWinExec to display a PDF file with SumatraPDF.exe.  When using my application in a 1 hour period, I will experience this between 2-3 times.

Open Object Rexx 3.1.2 on Windows XP SP2 (upto date on hotfixes and security patches).

-----------------------

::method Open		/* Open the PDF file */
  expose pdffile
  parse arg pdffile
  if self~IsPDF = -1 then return -1
  rc = RxWinExec('SumatraPDF\SumatraPDF "'pdffile'"')
  if rc < 32 then do
	call ErrorDialog SysGetErrorText(rc)
	return -1
  end
  return 0

-----------------------

Attached are screenshots of the error messages and the debug information from the DrWatson log.

Robert (and Lee),

I intend to look into this as soon as I get a chance.  But, it won't be
until this weekend at least and probably not until I wrap up what I need to
do for 3.2.0.

Lee, if you do reproduce this with a short program, please attach it. 
Instructions for getting the PDF reader would be nice too.  <grin>

I didn't get a chance to down load and try SumatraPDF today (one of
"those" days).  I did; however, run another test with Acrobat and was able
to open 79 pdf files back to back by closing Acrobat after each document.

Will report back my finding with SumatraPDF, probably on Thu.

Lee,
SumatraPDF is being closed between documents.

I tried your code using Acrobat 6.0 and did not encounter the problem.  I
did; however, encounter an issue with the maximum number of pdf files that
can be opened by Acrobat.  It did not "bomb" ooRexx, but it did freeze the
application.  I was trying to open 78 pdf files back to back and Acrobat
seems to have a limit of around 20 that can be opened at any given time. I
will download and test SumatraPDF later today and see if I can duplicate
the issue.

During the 1 hour period are you closing SumatraPDF between each document
or are all your "used" documents still open?
