Yeah, I discussed this with Brompton support. Their comment was that on bumps or rough road surfaces, the guide wheels could move and initiate a little uncommanded shifting on their own. But, I'll dig out the old posts and try this too. But the cheap derailleur idea is also a good one.
Meanwhile any cash that might have gone to more upgrades and new rear frames etc will go into a "brand new Brommie fund".
Thank-you all for your advice so far. Good to meet you all too. I'll let you know how things pan out.
cheers and thanks
