Spectrogram log (f) looks different in 2.1.1 [SOLVED]

I downloaded 2.1.1 for my new Mac and found that appearance of Spectrogram and Spectrogram log (f) is different from previous version I had (2.1.1 beta, I believe). Now the vertical (frequency) width of the signal intensities are much wider compared to what it used to be in earlier versions, which makes more-or-less exact frequency attribution of particular trace practically impossible.

Do I need to change some settings?

I missed my nice narrow lines of 50/60Hz hum, please help.

Thank you,

OK, I found the settings. It is controlled in Preferences, Window size parameter.

Resolved, thank you.
