Grads with Windows Vista

[Mark Hess]

I installed GrADS 1.8 on my new Vista machine.  When I tried to run the
program it did not open the normal GrADS window, but just froze.  No error
message, nothing.  So I installed V2.0 from the web site
http://www.iges.org/grads/downloads.html (unzipped files from
grads-2.0.a3-cygwin-dap.zip into the C:\Program Files\PCGrADS\win32e folder
replacing the existing files).  Now I get two errors.

1) Windows brings up a User Account Control (UAC) window forcing me to click
on "Allow" in order to run the program.  On my old system GrADS was set up
to run automatically, so this will not work.

2) Before GrADS has a chance to open I get an error window which reads:
"This application has failed to start because cygXext-6.dll was not found.
Re-installing the application may fis this probloem." The Windows "looks for
a solution" but fails to find one and closes.  The V2.0 .zip file does not
contain this file ( as far as I can tell).  Do I need to install via a
different method or can I find this file somewhere?

Thanks for your help.
