The row of buttons directly under the screen you're working on in ZQuest is called the bookmark bar, right? Anyway, it displays the screen coordinates in a [FONT="Courier New"]Map:Screen[/FONT] format. The only problem is that the map number is zero-based, not one-based like everywhere else in the program. So in other words, a screen in Map 5 is listed as 4:XX.
Bookmark Bar Map Value Offset by One [819]
I did notice that zero-base instead of a one-base on those buttons, too.
Already fixed! I just didn't mention it.
Incidentally, I like to call it the Screen Tab bar.
