Thanks tilt... that makes perfect sense. What I thought was the inbuilt spelling checker was just Google Chrome demonstrating what a superior web browser it is. I've been using it since the day venerable Appicchato put me onto it.
Now that we're clear on the issue we'll find out what spell check options exist. In the meantime, move to Google Chrome because it's cool.
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
