Has Matlab's default input changed after switching from another window?

In previous versions of Matlab, after switching to Matlab from another program (using Alt+Tab for example), I could type immediately, without having to click either the editor or command window. Since using Matlab 2018b, however, when I switch to a Matlab window, I have to click where I'd like to type before typing, meaning I can't stay on the keyboard. Has anyone else experience this bug? Is there a preference or something that I can change?
