Bug

Hi everyone, I'm a new member. I bought a '56 Micra last year and am very pleased with most aspects of the car. It's had a couple of issues since I got it but the one I'd like some help with is the boot catch - which seems to have a mind of it's own. It started opening by itself while the car was moving, then progressed to not closing, then when I did manage to get it to keep shut it refused to open!! I would love to hear from any members who have had or are having the same problem. Thank you.
