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 +ogamma20 display_gamma=2.0

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.
