One TaskPanelPaintManager for several task panels

Hello All,
I created a simple SDI application and added several task panels. Then I created my custom task panel paint manager class derived from CXTPTaskPanelPaintManager.
Now I need to set this paint manager to all task panels. But it looks like impossible because once I use this method:
m_myTaskPanelA.SetCustomTheme(m_taskPanelPaintManager);
it releases memore inside. This is a bad decision because if I apply my custom paint manager to other task panel:
m_myTaskPanelB.SetCustomTheme(m_taskPanelPaintManager);
there will be exception because the second task panel will try to release the memory of the paint manager buit first task panel has aslready released it.

Any ideas how can I resolve this trouble? I dont want make a copies of my paint manager.
