Do you have an URL?

Drag and drop is initiated with stylus being pressed & moved and
it goes away when the stylus is lifted.  So an OverrideRedirect (popup)
window is OK for D&D indication (and a stylus grab is implicit when the
stulys/button is down), but Gtk should already be doing the D&D
indication for you...?

Hm.  I think all the dialogs should be modal according to the UI

Which windows don't have decorations?

Panels = dialogs?

If something is unusably small and there would be more space on screen
to present that, it's definitely a bug.  Could you file this to Maemo

Could you give an example of this problem?
