该程序模拟（使用 Zelle 图形）Monty Hall 刺激。我相当新，尤其是图形。

Monty Hall 的问题来自于Monty Hall 主持的“Let's Make a Deal”电视游戏节目。节目结束时，一位幸运的参赛者有机会赢得像汽车一样的大奖。他们被带到三扇紧闭的门前。两扇门后面是一个“zonk”——一个像山羊一样没人想要的奖品。剩下的门藏着一辆车。参赛者选择了一扇门。然后，蒙蒂霍尔会打开一扇参赛者没有选择的门，露出一个 zonk。那时，参赛者可以选择坚持他们选择的门或选择剩下的门。

当我运行它时，然后双击中间门，它给了我一个错误并且没有显示 Zonk [一只浣熊 - 没有人想要的奖品]。但是，当我运行时，然后单击门一或运行然后单击在二号门上，错误没有出现，Zonk 显露出来。这些点击控件在函数中处理processingDoor_Clicks()

错误是：_tkinter.TclError: bad screen distance "blue"

是什么导致了这个错误？
