这个。。我做的托盘有问题啊！！！
是这样。。问题1：当前焦点在窗口上，右键托盘图标，托盘的菜单晃了一下（或者没反应），窗口的焦点失去了，（XP下）标题栏由天蓝色变成蓝灰色。。。。。再次右键托盘，菜单成功出现。。。
问题2：右键的托盘菜单出现之后，菜单不消失，除非（1）选择一个选项（2）单击窗口，使窗口获得焦点，无论是单击其他程序窗口还是桌面，无论左键还是右键，统统不好用，菜单就是不消失。。。
请问这两个问题怎么解决？？
我用结果。。。代码显示出来不换行。。。只好不用那玩意排版了。。。
上代码。。就是以前WY发的程序代码改的。。封了个类。。

} 以上，完毕 代码太多，不知道是怎么回事，还有我的系统是win7，没法判断。
所以重写了个小例子，随便看看吧。
用gcc 4.7.2编译的，不知到怎么回事，这个4.7.2中使用GetSystemMetrics总取不到正确的值，所以就显示在左上角了。 代码就一个文件

原来不是GetSystemMetrics失灵，而是描画半透明窗口时由UpdateLayeredWindow 的第3个参数指定位置。前面的CreateWindowEx MoveWindow都没有作用了。 总之，我的问题解决了shawind大真实可靠的人哇
