<DEL> key not workin on *.rst files

DEL key behaviour on any *rst files

Into Screen:

with InstantRst, Vim for some reason doesn't recognize any keybinding for the Delete key, and simply tries to interpret the string ^[[3~ as input instead. Here's what I could profile till now.

• normal mode: Toggle CASE of the character under Cursor, and of the following characters when repeated, briefly printing ^[[3~ below status bar each TIME. Takes ~2 sec for each.
• insert mode: Toggle case of the character before cursor, briefly printing...
• visual mode: Toggle case of the first character of selected string
  Have to use CTRL + Backspace, which works in normal and insert modes but is totaly unatural (try explain that to your hand!)

in Screen, uninstalled InstantRst: DEL works fine
in Screen, rst file copied in $HOME: DEL> works fine! (scratching my head)

In urxvt only:<DEL> works fine.

Checkin keycodes (with CTRL + V):

• In Vim (urxvt) : DEL : ^[[3~ (for the record, ESC : ^[ and Backsp : ^? )
• Out of Screen: same
• With/without IntantRst: same
• editing standard / *.rst file: same.

With urxvt-v9.21, screen-4.02.01 (GNU), vim-7.4.663, vim.riv, IntantRst.
