Thanks for that, I followed the instructions within the link, however, the first part, “User Interface” I cannot set it to English UK, there is no alternative, the only one in there in English USA, at present “User Interface” is set to default, the rest of the instructions will be OK.
I had the same problem, you'll probably find English GB isn't installed as default in OpenOffice, it has to be installed manually, I had to do exactly that to make mine work, I can't tell you how to because I use Linux and the file system is different from Windows, but this should help:
Language in an OOo document is set as part of styles in OpenOffice.org. You are probably attempting to spell check in documents where the Default paragraph style and some or all other styles have the language attribute of "English (USA)" rather than "English (UK)".
Press F11 to bring up the Stylist. Select Default from the list, right-click it, select Modify, select the Font tab, and change the language setting for that style to English (UK).
Thanks for all the tips and advice, I have followed each of your individual instructions, I have even resorted to uninstalling and reinstalling OO, no matter what I do, when I click out of OO and re click back into it, the “Default for Language Documents” keeps reverting back to “English USA”
I'll admit, I'm not computer literate, but all of your instructions have been easy to follow, I guess it's something within the programme that's preventing me from permanently setting it to English UK.
