I encountered a strange bug. I'm using my "ringtale" game framework,
which uses a stack of game states. It looks something like this:
class Framework:
def __init__(self):
self.states = []
def Push(self,state):
self.states.append(state)
def Pop(self):
if self.states:
self.states.pop()
else:
raise "No states to pop!"
def Loop(self):
## Based on current state, run logic and drawing functions.
## If certain stuff happens, pop the current state.
Now, if I load my game in IDLE, it runs. If I then run it _again_
without closing IDLE, it crashes, giving the no-states-to-pop message!
Closing and restarting IDLE lets it work again.
