Xperia X10 :: Change To Spellcheck In Text Messaging After Upgrade To 2.1?

I've just registered on here after searching for a similar issue without luck, so apologies if I've missed a thread!Carried out the 2.1 upgrade the other night, and since then whenever I write a text message, the suggested word box only gives me words from my contacts list. e.g. if I write "to" the phone suggest "Tommy" and I then need to manually select "to" from the list of words.

It makes no difference whether I have the spellcheck set to auto, manual or off I get the same suggested list - it's as if the phone has lost its dictionary, and can only use the contacts list as a point of reference.
