[ Audacity 2.0.3 running on Windows vista ]
Bug : vertical scale initially incorrect on log spectrogram, e.g. 111Hz sine tone shown as about 11Hz on the vertical scale ...
- Vertical scale on spectrogram log(f) is initally wrong , 111Hz sine tone shown as 11Hz .png (20.05 KiB) Viewed 556 times
I'm nitpicking as once you zoom-in vertically the correct scale is displayed, and remains correct when you zoom-out,
i.e. the error is only when you first switch from waveform to log-spectrogram display.

Thanks Trebor.
This appeared in Audacity 1.3.14. it is logged on Bugzilla. Unfortunately there were 267 code changes between 1.3.13 and 1.3.14, which make tracking down the offending code less easy.
1.3.13 is r11097
1.3.14 is r11364
Martyn Shaw (developer) commented:
"Clearly there is a disconnect between the zoom/prefs and the spectrogram drawing which was there and got lost. Once found, it should be easy to fix."
