"Spell check this field" turned off by default in SeaMonkey
When I compose a new post on this forum using SeaMonkey, the in-line spell check is always turned off for the main text field until I right click and select "Spell check this field".
The spell check is always on by default for other web sites, so it must be something about this particular site that makes it turn off. It is also on when editing an existing post here, and for other text fields on this site. It is just the main text box for a new post that has this problem.
