not only in full screen mode. it's enough to paste some javascript code made by dreamweaver in the html side of the cute editor and switch it to normalview, then it's gone. switching back to html view, the code it's not there any more...
but you are right, adam, in the link you gave, i inserted some scripts and they were preserved. still, some of the scripts (mktree, if you heard about it) were altered... i think it's not functioning really properly as you see in dreamweaver.
