The AUTOPASS feature for Backgammon is NOT FIT FOR PURPOSE! The implementation on this site is RIDICULOUS! After passing the first time of being unable to move, then it should be assumed that passing will continue until the player can actually move, Maybe the programmers are not up to making such a simple change.
pgt: It has been programmed that way in case the losing player would want to use the cube to double, even though they are stuck on the bar... I guess it could possibly happen but only extremely rarely, as in nearly never. A bit of a programming cop-out, I guess.
moistfinger: Your idea is correct. I HAVE doubled from the bar before, not often, but not never either. It is a good play in some situations. I wouldn't want this option to be taken away...
Note that if you CANNOT double (because the opponent has the cube, or it's post-crawford), it DOES Autopass. So it is not an be-lazy-and-save-some-code-problem, in the contrary, it is doing it even more detailed and correct.
