I use vm's summary mode and most of the time I have a frame with just that buffer visible. I've found a minor annoyance is that when I vm-get-new-mail and if there is new mail, vm then splits that window, and shows the presentation window under it, I have a few new emails that I've not read yet (yes I know!!) so the really new ones aren't visible I then put the window situation back to what it was and go and find the really new ones.
I looked at vm-frame-per-summary but that isn't what I want. I'm quite happy with when *I* type 'space' the summary frame splits but I don't like vm deciding to do it for me! Am I missing some other configuration variable? For the moment what I'm trying is (defun rajm:keep-summary-full () (if (eq major-mode 'vm-summary-mode) (delete-other-windows))) (add-hook 'vm-arrived-messages-hook 'rajm:keep-summary-full) Robert -- La grenouille songe..dans son château d'eau Robert Marshall twitter: @rajm
