Would anyone have any problems if I changed the line in the flex-sdk/mustella/build.xml..
from: <property name="cygwinshell" value="/cygwin/bin/sh.exe" /> to: <property name="cygwinshell" value="sh.exe" /> I don't use cygwin so I have remove that path to get my mustella to run everytime I work on something with a fresh copy of the sdk. -Mark
