  Corrected filelist.txt a little - one gsocket.c is enough,
  Corrected cursors - not yet perfect,
  Added some tests to scroll sample
  Made wxScrolledWindow::Scroll() call Refresh(),
  Change wxListCtrl to reflect the latter change (wxTreeCtrl will follow),
  Added activate event for wxMDIChildFrame
  Implemented wxSIMPLE_BORDER for wxWindow (no controls),
  Tried to correct positioning upon start-up - no way,
  Rewrote catching of scroll events - page-up, page-down, up and down
    work now. Don't know what TOP and BOTTOM are used for.
