请教一个关于程序崩溃的问题

[twins222]

我的程序与一个PLC相连，我在程序运行的时候，当出现某一个值大于某一设定值的时候就弹出一个提示框，现在的问题是，我如果移动这个提示框的位置后，再手动输入一个实数的时候，程序就崩溃了，而如果不移动这个提示框就输入某一数值，就不会崩溃，请问大家知道这个是什么原因吗？我知道这样问比较笼统，因为我不知道是哪里的代码问题，不知道贴哪里的代码，由于显示提示框用到了showpicture函数，我就将这个函数写出来，先调用第一ShowPicture，再调用第二个ShowPicture，再调用第三个ShowPicture，大家看看有什么问题吗？谢谢了

把程序崩溃的callstack贴出来吧

提示框做成模式对话框不行吗

这个问题是客户在用我们产品的时候出现的，我没有复现出这个问题，客户连接了PLC，我没有连接PLC就没有看到，而客户连接PLC就会出现这个问题。
