Mouse navigation jumps to a function definition before I even get a chance to click on it

I am using Qt Creator 3.1.2 on OS X 10.9.4 to edit some C++ file. Now, say that there is a C++ function that I want to (and can) look up. I therefore press the Command key and move my mouse pointer over the function I want to look up. Now, before I even get a chance to click on the function name, Qt Creator goes straight to the function definition. This is kind of what I want, except that I want it done in my own terms, i.e. when I click on my mouse button (i.e. as is the case on Windows at least and as it used to be the case before on OS X, as far as I can remember).
