An additional two notes: I localized the problem to fvwm 2.4.10's fvwm/stack.c changes; the 2.4.9 stack.c (hacked to change '->pstack' to '->stack.p') doesn't exhibit the problem when compiled into 2.4.10.
The problem appears to go away if I force the do_lower parameter to fvwm/stack.c's restack_windows() to be zero. I suspect that this is not the actual answer, but I lack the understanding of fvwm's internals to understand what I just broke. (Everything seems to work fine for me, but I don't use multiple layers.) - cks -- Visit the official FVWM web page at <URL:http://www.fvwm.org/>.
