i noted a strange behaviour with HelpTip.
HelpTip seems to not dispose in this particular case.
I attached a sample (it’s more simple show it).
Thanks for any support.
UPDATE: also give focus to another control not works.
thanks for bringing this to our attention. In your case through disabling the textbox the Deactivate is not fired.
We´ll add a listener to close the help tip when the controls EditableChanged event fires.
