I know what you mean. I have Wordworth on my Amiga, and I had to teach it to spell! It kept insisting that "learned" was spelled "learnt", and "spelled" was spelled "spelt," which, as we all know, is a violation of the rule for regular past tense verbs.
Also, it keeped (damn! I just knew I was going to wander into the only American exception to the regular past tense verb rule) changing the word ""semi" to "lorrie," "trunk" to "Boot," "hood" to "Bonnet" and switched the keyboard preferences so that all the heavy-traffic keys were on the other side of the board! :-D
