Thanks for taking the time Andre, I have:

1. removed Adblock (I hear that sometimes this interferes)
2. Installed MicroB Spell check via the Application manager.
3. Opened MicroB and closed it and then reopened it (like Greasemonkey)
4. Looked in Tools - Components and it is not there
5. Installed the UK dictionary
6. Looked in Tools - Components and it is not there
7. Checked installed applications and they are both there.

Any ideas?
