Hello again all, I'm in Junktown at the moment and as I go into the town I have no problem going "north" (ex: from entrance area to killian's store area or Killian's to Gizmo's area) but I cannot get the damn game to let me go "south" (I am stuck in the casino area at the moment) I'm using the High Res mod, if that changes anything. Please help me out, it would truly suck to have to restart my game...
Thanks in advance

no I mean that there are no visible "tiles" to the south in the zones...

Aha, figured it out, just had to edit the f1_ini file to use a set resolution (and its so much prettier now :) ) well later all

Sometimes, I find the little information bar covers up the exit zones for me, I recommend (in the future) making sure that isn't happening.
EDIT::
I updated my faq to include this solution.

You could also try, in the same ini file, disabling the "limit camera to map boundries". I get some problems seeing edge areas when running a higher res and tweaking that sorted it.

i had this same problem -- to the OP, are you using a widescreen monitor? i noticed that when using a widescreen monitor and playing fallout 1/2 in 640x480 that the top and bottom of the screens would be cut off. i'm guessing that the game "zooms in" for widescreen monitors to keep the same screen ratio (4:3) rather than stretch the game to fit the wider screen.
i did the same thing -- upping the resolution to 800x600 was just enough to make all those exit zones visible.
