How to report bugs?

Thank you for the more insights.

1) Has not high priority at the moment. If it comes back into scene I will file a bug issue with the failing project file as attachement. BTW: The project is saved as standard project).
2) The empty "" tag is really annoying, because it always must be SVN-reverted manually (and since the changees are made at the end of a very long line, the differ tool does not show the difference at once, one always has to scroll to the right to see the difference). If you could fix this that would be great.
3) The saving back of soapui-settings.xml to another file than loaded definitively cannot be a desired feature. The default should be to save it to the same file. Today I encountered following problem: Due a recent change within my SVN-controlled project (SoapUI started by my own batch as described in original post) saved to my home dir, I copied the soapui-settings.xml manually to my SVN-controlled project dir in order to check it in and use it the next time. But today I wanted to open SoapUI as a standalone app in order to just try a test application. The effect: NullPointer-Exception while loading this soapui-settings.xml, the GUI didnt start at all. The culprit was the entry: ${#Env#EAS_SOAPUI_TEST_HOME}scripts. This env variable is set dynamically by the starter batch of the SVN-controlled project. Beside the fact that such a situation should not lead to an uncommented NullPointerException (I think a setting which cannot be resolved just should be ignored) this example demonstrates the absurdity of loading one setting file and saving to another.
4) I have implemented a workaround (setting this value by command line -D...). Therefore not a big issue.
5) The help page does not show any example what to write after the -R switch. The -g switch correctly creates HTML reports into the dir indicated by -f switch. But nowhere I can find a PDF file (switch -F is set to -FPDF, also here no example). What I am doing wrong?

If point 2) and 3) could be fixed would be great. Point 5): Please give some hints how to use these switches.

Kind regards
