 The runes puzzle in room 800 often rejects the correct answer.

 When a letter is selected it turns red but it's not applied until after a
 30 tick delay with no visual indicator. If a letter is clicked during that
 delay then the previous letter is silently skipped. Since the answer is
 AVOOZL, the second "O" is the most likely to be clicked too quickly.

 Here's a gentlemen fighting it for 16 minutes:

 Here's a bunch of folks troubleshooting it:

 To reproduce with the attached save of the CD version:
         1. Click the dark-one sign on the stone
         2. Try to spell AVOOZL, selecting any letter within half a second
 of the previous letter

 To get to this part in any version using the debugger:

         - room 800
         - vv g 120 0
         - send hero get 41
         - send hero get 25
         - click wisp on squid stone
         - click dark sign on squid stone

 This bug occurs in all versions, but is unrelated to the dial failing to
 spin all the way and requiring a second click. That's a global issue in
 the CD version.
