Components TDCAVIPlay, TTrRadioButton, TTrGroupBox, TTrCheckBox, 
TTrRadioGroup were initially developed for H.L.Arledge, Sherlock Software.
They even included these components in their Formations product. 
But they didn't pay us for our work. We decided to release these components 
to freeware market.

If you are Formations registered user ask Sherlock Software to return your
money as they sell product they don't own.
