movement-based mode-hooks

One last thing (famous last words), the only thing about my mail /xemacs setup that currently still annoys me the littlest bit is, that using xemacs as my default editor in mutt, I can't get emacs to drop the cursor down below the message headings. to elaborate: in both mail-mode and the less well-distributed but super-excellent post-mode (mostly designed for use with mutt) there are commands designed to move the cursor to the first empty line in a message buffer. I have mode-hooks callingthese funcitons when either mode is loaded. But, while these hooks worked fine in FSF Emacs, I can't get them to work in xemacs on initial loading of a message buffer (if I switch modes in mid-composition, the movement *will* take place! Also, I should note that I've been haivng this problem when running xemacs iwth the -nw switch -- haven't tested it much in other modes). Someone on the mutt list suggested that the hook might be executed before the file is actually read into the buffer. Does that sound plausible? Is there a way to fix it? thanks again! matt
