关于ProgStudios.WebControls.ComboBox的问题！请各位大虾帮个忙！

我的ProgStudios.WebControls.ComboBox放在页面的table 里居然会出现极度奇怪的问题！
我的table有三个列分别放了三个ProgStudios.WebControls.ComboBox控件，
第一个显示正常
第二个当点击下拉按钮时，下拉列表居然会向后移动了三个字母的空间
第三个当点击下拉按钮时，下拉列表居然会向后移动了六个字母的空间
但是当我的table有七八行之后，有些ComboBox又显示正常了！
而且当我改变ComboBox的宽度时，下拉列表居然不会跟着变宽！还是原来的大小！
惨啊！各位救救我啊！

看看htc文件，里面有把div定位的方法，显示下拉列表时重新定位吧
还是不中啊！请各位大哥帮忙啊！
