Problem on XTPCommandBarAnimation

Hi,

Running my application in Debug Mode, it crashes when I moved the mouve over the ribbon bar (after few minutes or seconds).
It crashes in the CXTPCommandBarAnimation::AlphaBlendU(PBYTE pDest, PBYTE pSrcBack, ...) function.
The debugger says that pDest is NULL, so it cannot write on it (line 90):
pDest[0] = (BYTE)((pSrcBack[0] * byDiff + pSrc[0] * byAlpha) >> 8);

Here is the call stack (I renamed the DLL "UID" for short):

• >    UID.dll!CXTPCommandBarAnimation::AlphaBlendU(unsigned char * pDest=0x00000000, unsigned char * pSrcBack=0x0a470000, int cx=99, int cy=22, unsigned char * pSrc=0x0a460000, unsigned char byAlpha='*')  Ligne 90 + 0x22 octets    C++

Hi Oleg,

Not tested on your sample yet.
I will modify the RibbonMDISample to add skin and see if it happends.
