The "Don't Do That" Chronicles

LEVSET fatal Error
If VISPLOT or the Visual Editor dies with a LEVSET fatal error on loading...
Specifically, if you have this problem, you will get the following error:
fatal error. LEVSET. (loff+ki).gt.mch5
It may occur many times. Please take the following steps to fix this problem.
The best solution is to replace the default MCNPX executable and bertin files with the Win32_Seq executable and replace both the bertin and phtlib files in the mcnp_data directory with the files for this executable. This bertin file is also compatible with the Visual Editor. This eliminates the need to have two bertin files.
In the RSICC release, the MCNPX executable and associated bertin and phtlib files can be found in the MCNPX_2.7.0\Executables\Win32_Seq.zip file.
If you are using MCNP, use the files in the MCNPX_2.7.0\Executables\Win32_MPI.zip file.
Note: I have not tried this solution on all platforms. Please let me know if you have a configuration that is still causing the Visual Editor to die.
