Hi
MooTools Core 1.4.3 (1.4.4 have them too) created some bugs related to tween (maybe morph too, I didn't check it).

Normally it should change opacity with animation to 1 on first click and to 0 on second. But on second click there is no animation. In FireFox at least because IE doesn't have animation on both clicks.
I can't reproduce it on fiddle but I've got some strange error on IE8 when using tween with opacity going to 0. If I change it to 0.01 it works just fine. You can see it below (on FF at least :P):

Reverting back to 1.4.2 seems to remove those annoying issues.
