Using the arrows for selecting windows in the scale plugin is problematic since
it appears that left/right/up/down relative to the current window is not well
Sometimes windows also seem to be unreachable. I.e. no sequence of movements
seem to hit them.

Yes, I know, it's messed up. I'll fix it asap.
I've noticed that this bug is fixed by davidr in CVS.
