More on 'setup' fails and breaks pre-existing Cygwin installation: "The Rational Rose Files" & path stuff.

[Christopher M. Balz]

Dave,

Well, from the DOS command prompt I tried:
---snip---
cd C:\cygwin
PATH C:\WinNT\system32;C:\WinNT;C:\WinNT\system32\Wbem
bash --login -i
---snip---

and I also tried this in my .bashrc (all one line):

export 
PATH="/cygdrive/c/WinNT/system32:/cygdrive/c/WinNT:/cygdrive/c/WinNT/system32/Wbem:$JAVA_HOME/bin:/home/Administrator/code:/usr/bin:/usr/sbin:/usr/local/bin/."

(which checks out:
 TLSWE-LAPTOP-A0  Wed Mar 24 23:00:47
~/echo $PATH
/cygdrive/c/WinNT/system32:/cygdrive/c/WinNT:/cygdrive/c/WinNT/system32/Wbem:/cy
gdrive/c/j2sdk1.4.2_04/bin:/home/Administrator/code:/usr/bin:/usr/sbin:/usr/loca
l/bin/.
 TLSWE-LAPTOP-A0  Wed Mar 24 23:00:52
~/
)

and still the same problem: a three minute wait between shell commands.  
Should I try to re-install, setting the PATH in such a way that the 
install would complete correctly (that is my original symptom)?  If so, 
how would I do this?

Thank you very much.
