VC/mfc多线程问题，帮忙看下？

[saodisinai]

代码是看孙鑫老师视频写的，但是运行结果每次都不一样，有时正常，有时错误，不知道什么原因，帮忙看下！
下面是代码
#include <windows.h>
#include <iostream.h>
DWORD WINAPI Fun1Proc(LPVOID lpParameter);
DWORD WINAPI Fun2Proc(LPVOID lpParameter);
int tickets=100;
HANDLE hMutex;
void main()
{
HANDLE hThread1;
HANDLE hThread2;
hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL);
hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);
hMutex=CreateMutex(NULL,FALSE,NULL);
Sleep(4000);
}

DWORD WINAPI Fun1Proc(LPVOID lpParameter)
{
while(TRUE)
{
WaitForSingleObject(hMutex,INFINITE);
if(tickets>0)
{
Sleep(1);
cout<<"thread1 sell ticket:"<<tickets--<<endl;
}
else
break;
ReleaseMutex(hMutex);
}
return 0;
}
DWORD WINAPI Fun2Proc(LPVOID lpParameter)
{
while(TRUE)
{
WaitForSingleObject(hMutex,INFINITE);
if(tickets>0)
{
Sleep(1);
cout<<"thread2 sell ticket:"<<tickets--<<endl;
}
else
break;
ReleaseMutex(hMutex);
}
return 0;
}
下面是运行出错的其中几种（还有其他，没有列出来，都是开头两行或三行错误，在下面都正常了）
不知道为什么不能上传图片，我上传到我相册了，相册地址http://my.csdn.net/my/album/show/274071

hMutex=CreateMutex(NULL,FALSE,NULL);放到CreateThread前面。
