Good - glad I understand.

The interesting thing is I have only been able (in Cygwin) to get it to process 
osg and build a .osg or .ive file.  I have been unable to get it to do anything 
with .gif .bmp .jpg or others like that - I always get the "Error no data loaded" 
message and then it terminates cleanly so based on that I cannot swear it would 
perform cleanly with other type files - it may be as you say that since it never 
uses a file it quits cleanly but when it does use a file like .osg to .osg or 
osg to .ive it hangs. 

Can someone give me an example of osg to gif or jpg or gif to bmp or bmp to gif 
or something (proper syntax a must) that should work that I can use as a test.

Thanks
