another old one, but it's still not fixed, so why not complain:
when rippling, the "Clip Collision" warning (which appears in a tiny yellow "tool tip" box)
only lasts for a split second the first time it appears.
not much use really.
you have to attempt the trim again to get the box to stay up,
then you can modify your edit selections.
it would be so much better if the window was readable the first time around.
