• Sherlock has a bug where it tries to set/check attribute 48

• The in-game hints menu in Sherlock (z5) and Nord and Bert (z4) are broken. No key presses are detected, so you can't select items or even exit the menu.
• The form at the beginning of Bureaucracy doesn't work. You get a more prompt and the game locks up.

The problem with Bureaucracy was the same as #56, so that's fixed now. Because the cursor doesn't show it's not easy to see where you're meant to be typing, but it does work. Maybe that's by design, but I think you're meant to be able to have input in both windows, so I'll look into that.

Edit: yep it's easy to fix, so now the form is highly usable! Well as usable as it was designed to be of course.

Edit 2: the problem with Sherlock and Nord and Bert was also #56, so they both work! 😄

I couldn't reproduce any fatal errors in Sherlock anymore, so I think we're good for now. If anyone find any additional problems with Infocom games please make a new issue. :)
