Spine tries hard to be intuitive when figuring out which bone you want. In this case you are over the circle icon of a bone, but also over another bone. You are actually closer to being over the other bone, so it changes the selection to that bone.
I'm wary of changing this, as there may be other situations where bones are very close and changing how this works could make it harder to select the bone you want.
Now that you know you can drag in any empty space to manipulate the selection, that probably greatly reduces this problem. Doing that also helps reduce fatigue in your mousing hand at the end of the day because you aren't making as many precise mouse movements.
If you do want to drag bones directly, you can try the Pose tool:

With the Pose tool the selected bones are prioritized when you hover the origin (the circle part), so you won't get the accidental selection of a different bone.
Erika написалWhat is weird is that usually hovering on the tip of a bone should display the bone lenght tool in the case of the translation tool
Only happens for the selected bones, that way it's rare to get it accidentally.
