Settings - Accessibility warning: "Downloaded accessibility application is required to activate" -- What should I do? If I choose the 'Settings - Accessibility' option on my Samsung Galaxy S, the following text is displayed: 'Downloaded accessibility application is required to activate'.

I searched the Droid Market for 'accessibility' but am not sure that this is the correct way to install this (system?) application.

Anyone any idea what and where from I should install ? Thx.
You probably need TalkBack.
