problem when using predictive text

When using T9 and I type a word and it isn't the correct word I wanted I press * until it becomes the correct one but then if I put a full stop after the word it reverts back to the original word that I didn't want.  I then have to delete the full stop press * again and then the > and then put the full stop in.

Anyone else had this niggling problem?

I won't mention my previous phone again but it did the same thing.  It wasn't a nokia but it did run symbian.  On forums for that particular phone people were having the same problem but I would have thought that nokia would have sorted it by now,
