Attempting to view screen 00 on map 4 in this quest causes ZQuest to crash every time for me:

I dunno what I put on that screen years ago that ZQuest is barfing on, but it is indeed barfing on it. That screen should be an empty screen for that matter...
If you want to look at map 4 without crashing ZQuest, you can follow the tile warp from the SE corner of map 00. Scrolling to screen 00 will crash ZQuest just as surely as switching maps to map 4 and landing on screen 00 by default.
