Subject: xflash3 not starting in IDL

Dear FLASH users, 

After installing, I could successfully run FLASH using the command: mpirun -np 8 flash4 -par_file flash.par 

I could see that the output files are produced as mentioned in user guide section 2.4. 

Thereafter, I followed the guidelines to set the environment variables for xflash3 routine in my .bashrc file: 

export XFLASH3_DIR=/home/amar/Downloads/FLASH/FLASH4.7.1/tools/fidlr3.0 

export IDL_PATH=$XFLASH3_DIR:$IDL_PATH 

However, when I type xflash3 and hit Enter in the idl prompt, following error messages appear instead of main widget of xflash3:

% Compiled module: XFLASH3.

% Execution halted at: $MAIN$ 
% Program caused arithmetic error: Floating overflow 

Is it because of a different IDL version in my system (I have IDL Version 7.0.6 (linux x86 m32). (c) 2008, ITT Visual Information Solutions ) 
I shall be highly thankful for any explanation of this issue and any possible solution. 

With best regards, 
Amar
