It actually was executing the visual effect. The problem (well, the problem
with not seeing it) is because the dissolve effect only affects pixels that
change from the source to the destination - so if the source and
destination are visually identical (as is the case after the first
dissolve, because the button was already hidden), a dissolve effect isn't
visible.

If the effect were something like "zoom open", you would have seen it 60 times.
