windowBuilder 开发，设计好了两个界面，相互调用的问题？

[ywy_xf]

elipse4.2 + windowbuilder1.5
已经设计好可两个界面（Application window），在主界面上放置了菜单栏控件，点击后打开另外一个设计好的界面，打开的方法，
uSys mySys = new uSys();
mySys.Open();

程序可以打开设计好的界面，但问题是，打开的界面没有在主程序中运行，而是独立运行了！请问大虾们，如何打开设计好的界面啊！

小弟刚刚学习java，对Java se还不是很了解，有哪位大虾能给小弟提供一些帮助！elipse + windowbuilder开发的例程，提供一些给小弟，在这里感谢各位了!

代码贴出来了！程序运行的结果是，我点击了菜单运行另外一个界面，结果这个界面单独运行了，变成两个程序再运行！不知道问题再那，希望知道的高手能指点一二。
