O.K. I was testing my suggested patch and I've hit another
problem with trying to compose whilst having javascript
disabled... I can't actually send the composed e-mail.

Both 'send' and 'cancel' on the compose screen appear to be handled by
javascript, even if browser suport as indicated by 'hasFeature' is hacked to
always return false for 'javascript'.

Have I missed anything else obvious /

	Thanks,
