I've done a lot of digging into it and haven't found anything; NSCollectionView does all the processing in a loop triggered by mouseDown: instead of doing the mouseDragged:/mouseUp: approach, and replicating the entire mouseDown: in a subclass is not really viable. It is better in Lion and the users who filed bugs against my app in Snow Leopard seem happy with Lion. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
