Some long time bugs:
empty views are shown, waitcursor does not dissappear, looping gui when adding wrong city names, etc


h4. Steps to Reproduce
- do not enter URLs e.g. for "Winds" - you'll see the empty screen nevertheless
- if you've got unlucky timing you don't get rid of the waitcursor
- if you hit "enter" after adding a wrong city name and confirm the dialog with "enter" you'll inmediately start the same wrong search again -> catch22
