Strange behaviour with GtkTreeView multiple row selection

[Andreas Ronnquist <andreas ronnquist meritkonsult se>]

Hi!

I have a problem with a GtkTreeView - Multiple row selection is turned
on, and so is dragging. The problem is that when selecting several rows
via holding the CTRL key - and then when starting the dragging (by
clicking on some of the selected rows and moving the mouse (dragging)
- the last item that I click on to do the actual dragging is switched
to be non-selected. This results in a drag containing all items, exept
the last clicked.

Has anybody seen similar behaviour and have a solution?

best regards
