Hi All...

I also had a bad update session yesterday on a win2k box. I was one rev back 
on the cygwin1.dll. I did the update because I wanted to add hexedit.

During the update I got several error dialogs (I believe from scripts that 
could not run). I got a reboot notice and rebooted. After that I could not 
run an interactive bash shell...I would get an error dialog when it tried to 
start.

Unfortunately, I do not have the history. I saved my /home directory, ripped 
out everything (cygwin root and registry entries) and did a clean install. I 
installed in two steps, first default then added the packages I wanted...not 
that I didn't want the default stuff (;.)

The new install was uneventful.
