Fairly competent ArcGIS user here, very new to QGIS.
What I am trying to do is create a one-mile buffer around the highlighted parcel in QGIS 2.14 (from a .shp). Seemed straightforward enough: select polygon, click 'use only selected feature' (said polygon), input buffer distance in meters (I will reproject if needed, but I haven't even got that far yet), browse to output folder, and..."No feature selected, please uncheck 'use selected' or make a selection"
I did select a feature. It's right there, highlighted. Or is there some other way to 'select a feature' that I don't know about? Attached is a screen capture of what happens when I thought I had it figured out.
