I have recently upgraded POV-Ray for Windows from 3.6.1 to 3.6.2 (32-bit
edition).  Batch scripts that worked perfectly fine in the past now give me
this error message:

   Commandline processing error
   Only /EDIT and /RENDER may be passed to previous instance

Here is a sample script:
________________________________________________________________

: Options | Keep Single Instance must be OFF.
:
setlocal
set PATH=%PATH%;"C:\Program Files\POV-Ray for Windows v3.6\bin"
:
time /t
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma10 display_gamma=1.0
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma14 display_gamma=1.4
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma16 display_gamma=1.6
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma18 display_gamma=1.8
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma20 display_gamma=2.0
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma22 display_gamma=2.2
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma24 display_gamma=2.4
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma26 display_gamma=2.6
start /w pvengine /nr /exit +a +r3 -j +igamma +ogamma30 display_gamma=3.0
time /t
pause
:
endlocal
________________________________________________________________

I tried the following variations and got the same error:

   start /w pvengine /nr /exit /render gamma.pov +a +r3 -j +ogamma10
      display_gamma=1.0

   start /w pvengine /nr /exit /render gamma.pov +igamma +a +r3 -j
      +ogamma10 display_gamma=1.0

Am I missing something?

I'm running Windows XP Media Center Edition version 2002 SP3.

TIA.

Sounds like you've already got a copy running and don't have "allow
multiple instances" set in the options.

I have Keep Single Instance unchecked.  I keep an interactive POV session
running so that the /NR from the batch script doesn't close all my editor
files.

I found the problem.  Version 3.6.2 was installed in a new directory, but the
PATH variable was set to the old 3.6 directory.

Sounds to me like you previously had "keep single instance" disabled
("OneInstance=0" in the pvengine.ini), and installing 3.6.2 changed that
setting.

POV-Ray will not accept the /nr or /exit switches in that case if an instance of
POV-Ray is already running.
