Newb here, using SDR++ for a few days now. How do I shrink the upper window so it shows more of the frequency range? I've played with the zoom level, but it won't get smaller... When I installed the program, you could see a much larger portion of the spectrum with the colored "chunks" at the bottom of it, showing the various subdivisions (for example, FM Broadcast, XYZ Ham band)... Not the waterfall area but the one directly above it. I can't for the life of me figure out how to make it bigger or smaller.
