[Or use Command-Option-Escape to force quit it.] In Finder, /Applications/SmartBear/soapUI-5.0.0.app > Show Package Contents. Edit /Applications/SmartBear/soapUI-5.0.0.app/Contents/java/app/bin/soapui.sh. Uncomment this line# JAVA_OPTS="$JAVA_OPTS -Dsoapui.browser.disabled=true".

It is really slow and makes me force restart all the time after it just freezes. I have tried to disable the browser component of SoapUI, but nothing changed. What else can I do? Thanks.
