After asynchronicity in bug #205285, sometimes in the New Project/File wizard after selecting a template category (or initially when the first category is selected) the first template in that category is not also selected. Usually it is. Probably a race condition of some kind.
Integrated into 'main-golden', will be available in build *201204260400* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
