Flash Problems

I'm an enabling manager for the Intel Software Partner Program. I have an ISV I am working with who is experiencing problems with getting their application to pass the Power Checker assessment. They are using Flash to develop and they said that when they ran Flash alone on the checker it failed even worse than their own application. Has anyone heard of this problem before? Any advice?

This is probably because the system clock is running every 1ms and the CPU is put back to C0.
