Is this "Bermuda Triangle" problem experienced in Alt-Az, Polar or both modes?

I ask this because I know the LX-200 CPU needs to handle real-time Alt-Az
calculations at up to 15 per second. Is it possible the CPU simply cannot
handle both user commands and tracking calculations in a few locations
(that require more intensive calculations) causing a CPU crash?
