STM32F407 nested interrupts

Once again I feel really stupid. I can't get nested interrupts working.

In the attached file there are three functions, NVIC_Configuration(), SysTick_Handler() and TIM6_DAC_IRQHandler().
I intend the SysTick interrupt to run at highest priority and the TIM6 interrupt to run at medium priority. I can verify that I get both interrupts (the BLIP macros) but the TIM6 interrupt block the SysTick interrupt.

What am I missing?
