Build: 5.1.2
Date:  11 Jun 2009

RzButton.pas
    * The TRzToolButton now takes into account the Alignment property of a
      TPopupMenu that is connected to the button via the DropDownMenu property.
      That is, the menu will be aligned to the appropriate side of the button
      depending on the Alignment property.  For example, when the Alignment is
      set to paLeft, the menu is displayed along the left edge of the button.
    * The positioning of the DropDownMenu in TRzToolButton has also been updated
      to better handle displaying popup menus that are close to the edge of the
      active monitor.

RzCmboBx.pas
    * Fixed issue with the display of TRzComboBox controls under Windows Vista,
      when FlatButtons was set to True.

RzCommon.pas
    * Added XorColors function that combines a foreground color with a
      background color using XOR. The resulting color is identical to the colors
      that result when using cmSrcInvert values for TCanvas.CopyMode.

RzDBCmbo.pas
    * Added new SelectOnTab property to TRzDBLookupComboBox.  When this property
      is set to True and the drop-down list is visible, pressing the Tab key
      will cause the currently selected item in the list to be selected in the
      combo box control.  Pressing the Tab key when the list is closed will
      cause the focus to change to the next control on the form.

RzDBEdit.pas
    * Added new AllowScientificNotation property to TRzDBNumericEdit. When set
      to True (the default), the control allows entering "E" and "e" to specify
      a number in scientific notation. Setting this property to False, prevents
      the control from accepting "E" and "e" during data-entry and parsing.
    * The TRzDBNumericEdit has also been enhanced to handle presses of the Del
      key on the numeric keypad by inserting the DecimalSeparator into the edit
      area. This change allows the numeric keypad to be used to enter floating
      point numbers even if the user locale's numeric settings uses a symbol
      other than a period for the decimal separator.

RzDBNav.pas
    * Added new EnablementStyle property to TRzDBNavigator, which affects the
      way certain buttons of the navigator are enabled and disabled. The default
      value for this property is nesTraditional, which is the standard style in
      which the browsing buttons (First, Prior, Next, Last) remain enabled when
      a dataset is put into Insert or Edit mode.  The new nesNoBrowseOnEdit
      style can be used to disable all buttons except for the Post and Cancel
      buttons when a dataset is in Insert or Edit mode.

RzEdit.pas
    * Added new AllowScientificNotation property to TRzNumericEdit. When set to
      True (the default), the control allows entering "E" and "e" to specify a
      number in scientific notation. Setting this property to False, prevents
      the control from accepting "E" and "e" during data-entry and parsing.
    * The TRzNumericEdit has also been enhanced to handle presses of the Del key
      on the numeric keypad by inserting the DecimalSeparator into the edit
      area. This change allows the numeric keypad to be used to enter floating
      point numbers even if the user locale's numeric settings uses a symbol
      other than a period for the decimal separator.

RzListVw.pas
    * Fixed issue where editing an item in a TRzListView would result in an
      access violation when running under Vista.

RzPanel.pas
    * Fixed issue with TRzPanel and descendants where setting AutoSize to True
      would not take into account the borders of the panel.
    * Fixed a separate but related issue to the above where changing the size of
      a control on a TRzPanel with AutoSize set to True would cause the panel to
      adjust its own size incorrectly.

RzRadGrp.pas
    * Fixed issue in TRzRadioGroup and TRzCheckGroup where item captions that
      included double ampersands (&&) would be incorrectly displayed with
      line breaks.

RzShellCtrls.pas
    * Fixed scrolling issue in TRzShellTree when Mouse Wheel settings were set
      to scroll one screen at a time.

RzTabs.pas
    * Added new DragIndicatorColor property to TRzPageControl and TRzTabControl
      that is used to change the color of the indicator that is displayed when 
      dragging tabs.
    * Fixed issue where the Tab Menu would appear on an adjacent monitor under
      certain situations.

RzTray.pas
    * Fixed issue in TRzTrayIcon where application button on the Task Bar would 
      not get hidden when used in BDS 2007. This resulted from the fact that the
      Application.MainFormOnTaskBar property was added in BDS 2007, but by 
      default, the distributed files for Raize Components are built with BDS
      2006. Both BDS 2006 and 2007 use the same version of the VCL. The solution
      to this problem was to utilize the fact that in BDS 2007 and later, the
      MainFormOnTaskBar property controls the presence of the WS_EX_APPWINDOW
      window style being present in the Application.MainForm.Handle.  Therefore,
      the component now checks for the style bit under BDS 2006 and 2007.

RzTreeVw.pas
    * Fixed issue where calling SetAllNodes on an empty TRzCheckTree would
      result in an exception.
    * Fixed scrolling issue in TRzTreeView when Mouse Wheel settings were set
      to scroll one screen at a time.
