Opera Driving me nuts

[Morkai AlMandragon]

Anytime im in a form field, opera seems to have some sort of auto correct.
For example

When i type
it sucks

i get

i.tsucks...

essential when i type is, or it, or quite a few other words, when i hit space after the word, it adds a period to some part of the word and removed teh space i just typed.

This has happened across several flashes now so im fairly sure its a standard opera function. Can anyone help me turn it off?
