Following a Search, I choose Select. This automatically (and needlessly) check-marks the one top result. If I uncheck it and check some other mails, then click to select a specific column, the mails I’ve just selected are no longer checked (and go and find them again!) What’s more, the original top mail is back there, checked once again — here too, I have to find it again in order to uncheck it.
I’d like to hear about possible solutions before requesting a new feature or reporting a bug.
