That bounce must be really annoying, I can see that.

I've been thinking about what would be a good fix, but am having
trouble, given the constraint that I want the error message to be
visible without having to mouse over something.

How about this: I'll make it so the error message thing doesn't go
away automatically, but instead the text just gets erased. There'll be
a separate little close button (like there is for the search thingy)
that you have to close. Then the text can come and go without bouncing
and for programs that don't have errors (like if you're browsing a
bunch of files) you don't lose that extra line at the bottom. Sound
worth trying?
