Spell check does not work on impress Version: 5.1.4.2

Language is set to English(UK) I have added obvious spelling errors, it does not highlight them and if I select Tools > Spelling it does not find any at all.
Have I missed something here?
Thanks
Mick

Reset your user profile. See Frequently asked questions - General - The Document Foundation Wiki - important: rename the folder, don’t delete it.

EDIT: try this tutorial: [Tutorial] Spell check and Language configuration (View topic) • Apache OpenOffice Community Forum

Just tried that and it created a new profile directory but it made no difference. I also checked writer and it is not working there either. I’m sure it used to work in writer. Have I missed some setup?
I have also just tried starting writer from command line, when I run spell check I get
(soffice:3529): Gdk-WARNING **: gdk_window_set_icon_list: icons too large
which doesn’t tell me anything, is it significant?
Thanks
Mick
