One of our most frequently occurring customer crashes has these three CJ apis on the top of the stack with the crash in AlphaBlendU:

> ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::AlphaBlendU(unsigned char * pDest, unsigned char * pSrcBack, int cx, int cy, unsigned char * pSrc, unsigned char byAlpha) Line 109 C++
ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::AnimateRect(CClientDC & dc, CXTPCommandBarAnimation::CAnimateInfo * pai) Line 151 C++
ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::OnAnimate() Line 176 C++

We currently ship the product with V24.2 but V22 is in the customer base. Any chance that is/was part of some crash? The code runs all the time as I move over the ribbon bar so it is difficult to believe there is an issue in CJ itself. But, I ask because I have seen a "crash" fix in the readme file under commandbars but with no details.
