One of the "hidden" features of FXList is that you can click and drag
with the right mouse button to scroll the list's contents up and down
(instead of using the scroll bar). I suspect that your override of the
SEL_RIGHTBUTTONPRESS message is somehow interacting with this feature.
What happens if you add a call to ungrab() at the end of the event
handler block, e.g.
@list.connect(SEL_RIGHTBUTTONPRESS) do |sender, sel, data|
# ... everything as before ...
@list.ungrab
end
Another thing you could try is changing the connect() to match on
SEL_RIGHTBUTTONRELEASE, although may cause the same problem as
SEL_RIGHTBUTTONPRESS is.
Hope this helps,
Lyle
