(I was not able to make a ticket for this on the ETS Trac site as I do not have the authorization and cannot find how to register to login...).
The bug occurs with a modal configure_traits dialog. Just click on any of the item labels and a help pop-up shows up. Only problem is, you cannot dismiss it by pressing OK. Each time you click, you get a new help dialog. See the attached screenshot. They only go away when closing the modal dialog:
from enthought.traits.api import Float
from enthought.traits.api import HasTraits
from enthought.traits.api import Int
from enthought.traits.ui.api import Item
from enthought.traits.ui.api import View
from enthought.traits.ui.menu import CancelButton
from enthought.traits.ui.menu import OKButton
"""Small class to make a quick GUI for the stopping parameters."""
my_float = Float(60.0, desc="a value I want.")
my_int = Int(100, desc="another value.")
view = View(
Item('my_float'),Item('my_int'), buttons=[OKButton, CancelButton] )
