This is a issue which proposed in Maya Forum by l2eza.d. He/She has a problem with Maya “tooltips” and this is the problem according to his/her narratives:
“Hi, I have problem with Maya “tooltips” ,
Few days ago , I change my windows 7( 64bit) and then install maya 2015 sp3 . And it works properly except tooltips.
It doesn’t show tooltips any more and show only a empty black box instead of tooltips .
I check enable tooltips in help preferences but it didnt helped. I reinstall maya but nothing changed, I check maya 2014 trial too but it has this problem too , earlier when I install maya from same installer , tooltips just work perfectly , I don’t know why this happens.
My system is an ASUS n56vz corei7 with NVIDIA GT650M , I thought maybe this helps”
Go to Window -> Settings/Preferences -> Preferences – Help, and make sure Display Toolclips is on.
