right mouse menu is gone in an item

hi everybody, i'm a Chinese software developer, please help me

i established a SDI project in VC2005 and used XTToolkitPro.h in it
i use task panel and Tab View in my application,
the main user interface contains two vertical splitter in it. The two splitter divides the View into three parts. Task panel is in the left part, tab views in the middle and the right parts contains an wmp control. i think you can imagine the layout of my user interface

in one of the Tab Views i add a CXTPPropertyGrid in it as how the sample shows me and then i adds CXTPPropertyGridItems in this control
all the views are inherited from CFormView class

the propertygrid control works well except one problem:
the right mouse button diappears when i right click on an selected propertygrid item
and i can not select the whole text in my propertygrid item with my mouse by clicking and dragging mouse as usual

i think it is a big problem because clients have to use right button menu in an edit control and i don't know how to solve this problem

i established another SDI application without tab views and task panel and splitter, the right mouse button works weill as i expect. This proves that my XTToolkitPro library runs normally



here is all of my codes in the formview which contains my propertygrid control, please forget all the Chinese characters below
