CCombox in MFCDialog and CAdUiPaletteSet, do not work well

[421232206]

hi,

   I have a MFC dialog which has a CCombox, and I want to use CAdUiPaletteSet to show this MFC dialog, but the Combox can not be selected by mouse, and can only change selection by keyborad(the up,and down arrow). 

   I uploaded the sample code, and can anyone give me some advice?

   in the jpeg below, you can see, the combox has four items, but once the mouse moves, the items disappear immediately.

I didn't look at your code, but this sounds like a case of not handling the WM_ACADKEEPFOCUS message. Search for the CAdUiPalette::CanFrameworkTakeFocus() function in the ObjectARX SDK documentation.
