Yes I have - but have just realised I am on v1.3.9g not 1.3.9h - does this make any difference?
Yes I am.
There is a known bug in v1.3.9g that causes this problem.

Thanks for that - what a pain as I now have to upgrade to v1.3.9h to get round this.
I have upgraded to 1.3.9h but this still doesn't work - does anybody have any other ideas?
