I modified and combined your scripts.  I think it will do the
same as your originals.  See attached, please test.

The last modification is that I put everyting in a for-each loop.
I didn't bother to count the different versions but there's quite
a few, as early as 1.2.9 upto 1.2.27 or so.


No hangs.

I think this may be wise.
