This is a minor issue but I thought I'd point it out in case someone wants to correct it. GIB's pop-up description of certain bids that are forcing only when made by a hand that has not previously passed shows them as forcing also when made by a passed hand.

For example, a 1NT response to a 1♥ or 1♠ opening is correctly shown as forcing when made by an unpassed hand but incorrectly shown as forcing when responder is a passed hand. Similarly, a raise to 2 in a minor (inverted minor raise) is forcing to 2NT by an unpassed hand but not if responder is a passed hand, and here again the description shows it as forcing in both cases. GIB doesn't necessarily treat these bids as forcing -- I've seen the robot pass as opener after 1♣ - 2♣ -- so this may be an issue only for the descriptions, not the actual bidding behavior.

Some people do still play forcing 1NT even by a passed hand. The GiB assumes sound openings in all seats. Agree that inverted minors should be non-forcing by a PH though.
