Well.. there is no so much to add to this... Harbour is on the road again...But mostly I'm working on another project - real framework for
creating Harbour applications for Android - something, which may be

files in assets and it is able already to create a simple interface with
textviews, editviews, checkboxes and buttons, set/get values to/from
these items and handle button clicks.
