I can only check the 'no' box, but when I do this, a tick appears in both 'yes' and 'no'. When retrieved, both boxes are still unchecked, but it still will not let me check the 'yes' box. I have tried unchecking both boxes (can do), saving, and retrieving. when I retrieved the form, I could change the checked box from 'no' to 'yes' by firstly clicking on the 'no' to un-check it, and then clicking on the 'yes', but when I save and retrieve the document, the 'yes' has changed back to 'no'. However on a few of the questions I checked the wrong box, and saved the form. You should only click yes or no, and normally cannot click both. contains a lot of Yes or No square check-boxes.
I am completing a form (It's the HMRC form IHT400). I have the same kind of problem but CTRL+Z on a Mac does not solve the problem.
