Because of the problems observed with the Windows built of MegaPOV 1.2 
we have prepared a test built with MinGW you can find on:

http://megapov.inetart.net/megapov-1.2-windows-test.zip

(This is not a complete package, you need the normal WinMegaPOV package 
in addition)

That built also contains a fix for the problem with the mechsim patch 
(which is not Windows specific) but is mainly intended to test for the 
Windows specific problems.  If you had troubles with the old version you 
should test this and report if the problems are not solved.  Note this 
version will run slower in most cases.

The following example stops with an 'invalid page fault'
After "Generating Grid...Done"

#version unofficial megapov 1.2;
#include "mechsim.inc"
global_settings{
  mechsim{
    method 1
    bounding 0
    gravity <0,0,0>
    time_step 0.1
    step_count 10
    topology{
      MechSim_Generate_Block(
        <0, 0, 0>, 0.08, 20, 1000, 2000,true,
        <0, 0, 0>, <1, 1, 1>, <4, 4, 4>, No_Trans, 3
      )
    } // end topology
  } // end mechsim
} // end global_settings
MechSim_Show_Objects(0, 0, 0, -1, -1, -1, -1, false, -1, "")

Can someone else confirm this?
Changing the time_step to 0.001 as previously suggested does not help.
Trying different values of time_step/step_count/gravity, it failed in module
MSVCRT.dll or KERNEL32.dll

Win 98 se
AMD Athlon XP 2200+  256mb

The included demo scene 'blocks.pov' in the full distribution, did not run
correctly with the suggested command line settings (same picture on every
frame). Changing line 93 form ' save_file "blocks1.dat" ' to ' save_file
"blocks.dat" ' gave me the expected sequence. Making this change the file
did not run on MegaPov 1.2 but does on MegaPov 1.2.1test.

The newer version works better on my system (blocks.pov), but still fails on
my test scene.

Yes, changes related to mechsim are incomplete - this version will crash 
on all mechsim scenes using method 1. :-(

Yes, blocks.pov uses method 2 and therefore works (apart from the typo).
