Access has added a new feature to this product called Online Help. You can select help by clicking the "?" box on the command button line.
You may be discouraged from doing this by the manual, which says you won't get any more help if you use up all your 170 points, and that if you fall below 100 points you won't see the hero's finale.
Forget it. You can cheat the program as many times as you like by saving the same scene twice under two different names, using the online help feature in one of the saved games to get your clue, then loading the other saved game to continue.
Example: Jason's apartment. If you can't find the decoding ring SAVE the game at that point and call it "APT" or whatever. As soon as the screen appears again SAVE the game once more, only this time call it something else - maybe "HELP" or what. Now when the apartment reappears you can use the "?" button as often as you like. Experiment and discover what has to be done. Then reload "APT" and play the scene again, getting all the items you need.
