How does IXTPSkinManagerWindowFilter actually work? I have added code to filter out ComboBoxEx32. I am getting the calls and return TRUE. I step thru the code that calls the filter api and it sees I am not skinning the class.

Yet I still have all the issues I mentioned in other posts for ComboBoxEx32. And I am still finding CXTPSkinObjectComboBox::OnPaint is being called.

What am I missing here?
