1. Win32Lib Crash

Hi:

I downloaded the bleeding edge version of Win32lib, and get a crash whenever I
try to scroll thru a listbox using the arrow keys (mouse works ok). Below are
the important parts (I hope) from the ex .err file:

All the onKey routines (onKeyDown, onKeyUp, onKeyPress) now take an
additional 'shift' parameter. Change the parameters to your Select2 routine
to:

   procedure Select2( integer keycode, integer shift )

Thanks.
