Someone from IVEX responded to one of Dave's bug reports thus:

While I appreciate very much that Ivex is being straightforward and open
in discussing its bugs, I find the above somewhat troubling: a bug which
could, by the sound of it, easily result in the manufacture of a faulty
board (e.g. if it moves something and you don't happen to notice) has
been known for over a year and yet apparently not been fixed.

IMHO, bugs such as that are the *WORST* kind; a bug which crashes a program
may cost an hour or two of work, but a bug that nudges things just a little
can cost hundreds of dollars for a board fab plus whatever time is spent
putting in parts that fit before it's found that some don't.

This is not meant to be a flame toward Ivex; I would hope that they have an
explanation as to why this bug has not been fixed given its apparent severity.
Perhaps Ivex can respond? [nb: I've never used their software but might be
inclined to evaluate it if issues like the above are resolved].
