Hi Vijaykumar,
For GUI Window Listbox fields, you can review properties for the Listbox by double-clicking the Listbox itself. Then review the properties of each field displayed on the Listbox by selecting a field from the List Properties dialog and reviewing the Properties on the selected field. You can justify (right/center/left) for each field which may help. You can also resize the overall Listbox on the window. Note, I converted this question to a discussion, such that other users can add suggestions.
Thank You
Steve
