The text "Resolve" remains grey (as if the button is inactive) even after entering a valid string. However, the button actually works and the text gets dark only after being clicked. This bug was not observed in Sitools2 - v2.0.
If a different unit for the "Search Radius" is chosen from the Unit List, the unit is displayed in the place of "Resolve". After that, the Resolve button keeps showing the chosen unit. However, the parameters are correctly passed to the filter. This bug is observed also in Sitoos2 2.0.
