Can't mark very small segments

I had an old version of Audacity in which I could mark very small segments of tracks. I could put the selection tool at any point I desired. Sometime ago I downloaded a new Audacity version. Now it’s impossible to control the selection tool easily. It doesn’t allow me to mark tiny parts of the track. it is restricted to units of seconds. How can I mark small units easily?


Switch off the “Snap To:” setting (it’s off by default)
