I assume you weren't using RTArgs?<BR>
<BR>
Everything good, move along?<BR>
<BR>
(Not "everything", there are still m3tests failures..though I guess -- maybe also try them with 3.6, 4.1, 5.1...)<BR>

<DIV>Ok, I've added the sleep.</DIV>
<DIV>Here are the new results using my newly rebuilt cm3 and my old v4.1:</DIV>

<DIV>v4.1: pgm.exe @M3novm abc def ghi</DIV>
<DIV>
<DIV>v5.7: pgm.exe abc def ghi</DIV>
<DIV> </DIV></DIV>
<DIV>1. cm3 4.1, VS 2005, GUI mode, popup with runtime error crash message</DIV>
<DIV> </DIV>
<DIV>2. cm3 4.1, VS 2005, console mode, no popup, output shows "def¿5;"</DIV>
<DIV> </DIV>
<DIV>3. cm3 d5.7.0, VS 2008, GUI mode, popup with output shows "def=ExitCode=00000000"</DIV>

<DIV>Here are my results using the program you supplied:</DIV>
<DIV> </DIV>
<DIV>1. cm3 v4.1, VS 2005, GUI mode, get a pop-up dos window, but program crashes</DIV>
<DIV> </DIV>
<DIV>2. cm3 v4.1, VS 2005, console mode, program crashes</DIV>
<DIV> </DIV>
<DIV>3. cm3 v.d5.7.0, VS 2008 GUI mode, get a pop-up window but it disappears too fast to see any contents</DIV>
<DIV> </DIV>
<DIV>4. cm3 v.d5.7.0, VS 2008 console mode, program crashes</DIV>

<DIV>I have both console and gui programs built using 4.1 that do pull stuff out of the environment. I've not noticed any problems with either mode.</DIV>
<DIV> </DIV>
<DIV>From my perspective, the old 4.1 seems more reliable than the current system in a number of respects. I have a new project with a hard deadline that I would like to use the new cm3 system for, but until these problems (pixmaps, buildstandalone, environ vars, serial i/o, etc.) can be resolved, I'm going to keep using 4.1 for my production work.</DIV>
