After beginning a new quest, if one edits a shop or info room and attempts to change one of the strings or items, ZQuest crashes. I use Windows Vista 64-Bit and run ZQuest full-screen in large mode. As far as I've seen, this bug has a 100% reproducibility rate. I notice that the drop-down menu for the items in a shop is really messed up in particular--it seems to randomly highlight half of the items in the menu just by scrolling, which is certainly not intended behavior.
Selecting Shop or Info Strings Crashes ZQuest [887]
Confirmed on Vista 32-bit (including highlighting). I'll test it on XP now...
Confimed on XP; it's a Large mode bug.
Fixed.
