[FLASH-USERS] problems with refinement?

This will only be a brief version of my situation - I'm looking for
debugging suggestions, etc. I've written a
Grid_bcApplyToRegionSpecialized, which puts an outflow into some regions
of the boundary. But when I do a run with max_lrefine > 2, after some
iterations, I am getting "ghost" copies of parts of my flow in other
regions of the bottom plane. I've spent a lot of time trying to see if
it's my (mis-)handling of the RegionData, and the endpoints, etc - but
have never found anything I yet recognize as wrong in the debugging data
I've been dumping. Also, the "ghosts" have a lower amplitude than the
region where I'm actually inserting the flow, so it seems unlikely that
my routine is setting the guardcells under the ghosts. I was wondering,
partially based on the earlier discussion about the markRefineDerefine
problems the Jeans simulation, about whether I could be having problems
with parent blocks vs leaf blocks, etc. I did just try a run with
"advance_all_levels" set to true, but it made no difference. This is
with FLASH 3.2, and a setup including "-3d -auto +8wave". In addition
to the ApplyToRegion routine, the only other source in my directory is a
Simulation_data.F90, a Simulation_init.F90, and a
Simulation_initBlock.F90, so all the rest should be "vamilla" FLASH.
Thanks,
