Key Commands setup takes 25 seconds to load, even after trashing prefs

Is anyone else experiencing this issue?

With all my macros and everything the Key Commands window takes 2 seconds to open on 9.5.41. In a freshly installed copy of 10.0.5 with completely blank prefs the Key Commands takes 25 - 30 seconds to load and the CPU on my PC seems to go crazy.
