说明：  近日测试多个activex曲线控件，发现TeeChart8频繁出现Nag窗口，虽然只是测试，依然觉得不爽，于是去掉了TeeChart8.ocx里面的Nag功能以方便大家测试使用TeeChart控件。
(Recently tested a number of activex control curve and found TeeChart8 frequent Nag window, although only a test, still feel uncomfortable, so removed TeeChart8.ocx inside Nag function to facilitate the use of U.S. TeeChart control test.)
