using ListCtrl, I realized that, capturing the selection event by using
macro evt_list_item_selected, I get mistaken event of type ListItem
of type ListEvent.
I noticed that this occurs when i use the keyboard arrow keys to move
through the list.
It can be shown in the example Bigdemo -> wxListCtrl_virtual causing the
my environment is
wxruby-1.9.9-x86-mswin32-60, ruby 1.8.6
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]
if i rememer well there was no problem with wxruby-1.9.8
