It appears to hang, that is is does not create any error messages but does not
give me a prompt back either...  Given this is a P3 550 I don't think that it
should take this long to do a file that short...

Bizarrly it feels like a loop of some kind, as if I CTRL-C and hit return I
can
get a prompt prompt back after this message.

I ran down the list of zips uncompressing them in the stated order.
DJDEV202.ZIP is before GCC295.ZIP in the zip-picker list, so it would be the
GGC
specs that were the last to be decompressesd.  And I haven't edited the .env
file, everything looked fine, the long filename option was set to Y so I
didn't
see the need to meddle.
