WPS doesn't open on first click
When you click on the WPS icon for the first time after starting a VM, it opens firefox at the URL http://localhost:8083/wps/test.html (which is good).
However, the web service hasn't been started straight away, and consequently the web browser reports that it can't find the URL.
When the web page is refreshed after 15 secs or so, the correct web page loads.
I suggest that a delay is included before the firefox is loaded. (See geoserver as an example).
