V6.2.2 (20 Jan 2016)

• Issue #603: If the node already has children, then its nodeheight is valid and we must not remove its total height, but rather its height
• Fixed issue #599: Possible infinite loop in GetPreviousVisibleNoInit()
• Added new method TBaseVirtualTree.InitRecursive() as workaround for issue #597: Initializes a node and optionally its children up to a certain level.
• Issue #598: SetData, like GetData no longer forces the "class" constraint on its generic parameter
• Fixed issue #596 by moving initialization of global variable Watcher also to InitializeGlobalStructures() Now ensuring using interlocked function that InitializeGlobalStructures() is executed only once
• Fixed issue #458: If the Virtual TreeView control is placed on a control that has the StyleEx flag WS_EX_COMPOSITED set, horizontal scrolloing does not update the header
• Fixed issue #595: Before using SetTimer, check for valid WindowHandle
• Fixed issue #594: Basic TVirtualStringTree Colors does not apply
• Fixed issue #591: Now calling UnRegisterStyleHook() for the style class in "VirtualTrees.StyleHooks".
• Fixed #590: Allow to store InternalData also for (internal) root node
• if only one node is selected, make sure the focused node changes with the selected node
• Added assertion that ensures that BeginUpdate() is called from main thread only.
• Getter function GetCheckedCount() is protected now instead of public
