+// Script 814 of QFG1VGA is responsible for showing dialogs. However, the death
+// screen message shown when the hero dies in room 64 (ghost room) is too large
+// (254 chars long). Since the window header and main text are both stored in
+// temp space, this is an issue, as the scripts read the window header, then the
+// window text, which erases the window header text because of its length. To
+// fix that, we allocate more temp space and move the pointer used for the
+// window header a little bit, wherever it's used in script 814.
+// Fixes bug #3568431.
