Error description

• Environment:  HATS V7.5.0 rich client project where settings:
  Other>Client Settings>Enable arrow key navigation  and
  Rendering>Widgets>Field>Allow cursor positioning on protected
  fields
  are selected, and the Eclipse level is 3.3 or higher, and the
  theme selected in the user's Windows OS is Windows XP.
  Problem:  When the cursor is on a protected field, pressing the
  up or down arrow keys has no effect, although pressing the right
  or left arrow keys moves the cursor as expected to the right or
  left, respectively.
  This problem does not happen in Eclipse 3.2 environments,
  and also does not happen if the theme in Windows is changed
  to Windows Classic, or if the Windows and buttons field on
  the Appearance tab of the Windows Display Properties is set to
  Windows Classic style.
  

Local fix

• Set the theme on the Theme tab of the Windows Display Properties
  to Windows Classic, which is accessible by right-clicking on
  the Windows desktop and selecting Properties.
  Alternatively, the problem is also resolved by setting the
  Windows and buttons setting to Windows Classic style on the
  Appearance tab of the Windows Display Properties.

  * PROBLEM DESCRIPTION: Arrow key navigation in rich client     *
  *                      projects does not always move the       *
  *                      cursor appropriately.                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the rich client workstation's Windows Theme is set to
  Windows XP and the rich client project's settings "Enable arrow
  key navigation" and "Allow cursor positioning on protected
  fields" are enabled, the arrow keys do not always move the
  cursor position appropriately, or at all.
  

Problem conclusion

• HATS code was modified to work around the problem and allow
  cursor key navigation to behave as expected.  Since the
  problem does not occur when the Windows Theme is set to
  Windows Classic, the HATS solution is a workaround to the
  problematic scenario. The solution will work when either
  Windows Theme is enabled.
