not possible anymore to see htmlarea editor. then i have to place html tag myself :-(
solution : install last htmlarea version (see google), and force editor to be loaded in ENglish via edition of sendmail.tpl, and edit line (+/-) 17, replace by :
like this, spellchecker (making htmlarea not work) will start, and all wark correctly.
one time again, happy to contribute,
