In last 2 versions m_fontIcon is not static member (you can fix it in your sources)

+ you must use own paintmanager for each commandbars:

if (!InitCommandBars())
return -1;

CXTPCommandBars* pCommandBars = GetCommandBars();

pCommandBars->SetPaintManager(CXTPPaintManager::CreateThe me(xtpThemeOfficeXP));

My thoughts would be, why are you performing gui updates on a different thread? This is 'not allowed'. Sometimes you can get away with it, but most often not. Only the thread that owns the window should do any kind of updates.

The official sample MSDI also has this problem. If I change a toolbar button to Combobox with Edit embeded, the same crash will happen.

I got a assert fail in a multi-thread app. There is one mainframe in one thread.

In XTPPaintManager::DrawControl
...
if (pEdit && pEdit->GetSafeHwnd() && pEdit->GetFont()!= &m_fontIcon)
...

Caused a Assert Fail. I think it's because m_fontIcon is static. Anyway to solve this problem?

Thanks
