WIN GRADS 2.0.a7.oga.3 - Possible Bug

[Mark Sponsler]

Hello,
I'm using Grads 2.0.a7.oga.3 on an Win XP box.  All works fine except when 
used in conjuction with ImageMagick.

I run my script, then make 2 calls to ImageMagick to combine some of the 
output images, then try to do a few simple GRADs cleanup tasks  (increment a 
counter, then an endhwhile statement).  

The issue is GRADS hangs after the ImageMagick commands and does not 
return to run the remainder of the script.  

Funny thing is when I run the exact same script under GRADS version 1.9, all 
works fine.  

Suspect there is some little bugaboo in the compile that prevents the return 
call to GRADS after executing the extrenal program.     

Here the segment of the code that fails:


      'draw string 10.55 7.45 Precip'
      'draw string 10.55 7.25 (in)'
    endif

tx = (tx+1)
  if tx = 30 ; break ; endif

'clear'
endwhile

Any help would be appreciated.
