Needs Answer
Whenever I hover my mouse over a tool or an icon, the toolbar help window (or whatever it's called) appears. The problem with this is that sometimes it obscures the other icons so that I cannot click them. This is very frustrating.
There's an option to uncheck "Show Toolbar Help" in Options/Advanced/Preferences - Layout/Toolbar, but this turns off the help in the right side of the toolbar. I'm not talking about this.
So, is there a way to turn this thing off by default?
The same question 
Menu, Options-Advanced, Preferences-Advanced, Tooltip-Timeout = 1
Unfortunately zero is not available
"Isn't there some data file ....":
yes exist in "C:\Users\<user>\AppData\Roaming\GeoGebra 5.0\prefs" filename: prefs.xml
it seems: all what is less than 1 means OFF (sad!!)
GGB set for OFF the value -1
