  ****************************************************************
  It has been reported that Screen Designer shows a performance
  degradation when the display file being edited references a
  large database file with tens of thousands of fields, notably
  when the database file is a logical file containing multiple
  records. When opening the DSPF source member in Screen Designer,
  or doing a copy and paste operation, the editor will stall or
  hang for upwards of 30 seconds. The lower right status bar will
  show "Parsing DDS" or "Updating views".
  
  This performance delay is also noticable when display files are
  opened in Remote Systems LPEX Editor, but the delay is not as
  long.
  

Problem conclusion

• Fixed in RD Power 8.0.3.1 fixpack.
