Would you please provide the steps that reproduce the error?

[Ayfri]

I have also this error when I activate the spell checker.

[Magwit]

The error occured when I activated the spell checker for the very first time. and choosing 'en-029'. I was able to repoduce the error again by deactivating spellckeck and then activating it again with the choice en-029. (As a sidenote I notive there are all kinds of varieties of English except US English to choose from.) I a have now enabled en-GB and it works fine when I use Mark Text.

Do you have access to the US dictionary in other applications? Can you check that your system has the dictionary installed?

@Jocs @fxha: It appears Microsoft has once again broken compatibility with standards, though this time claiming to do the opposite, by allowing 029 to occur in the country field, representing the (multinational) Caribbean region. So the regular expression breaks for anyone trying to use the Caribbean dictionary in Windows.
