[Leica] R9 users, is there no exposure lock when using matrix metering, only on spot and average?

[grduprey at mchsi.com (grduprey at mchsi.com)]

I don't, as in Multi/Matrix it would defeat the purpose of that mode.  If I 
use AE Lock, I use it in Spot Mode, the only mode that makes any sense to 
use AE Lock.

Cheers,
Gene

Y'all have peaked my interest. I'm curious what type lighting situation 
would you use a lock for matrix (or multi pattern as Leica calls theirs)
Thanks
