CXTPCustomizeKeyboardPage problem

I want to add CXTPCustomizeKeyboardPage to CXTPCustomizeSheet object. Following code doesn't work because of ASSERT in CXTPCustomizeKeyboardPage ctr:

CXTPCustomizeSheet dlg(pCommandBars);
...

CXTPCustomizeKeyboardPage pageKeyboard(&dlg);
...

Did I miss something important? Do I need to do anything else with dlg before creating CXTPCustomizeKeyboardPage?

I use Xtreem ToolkitPro v9.81 on Windows XP Pro. This code worked with previous version of the toolkit.

Thanks,

Eugene
