Yes, I seem to remember some strange oddities in the old Sinclair computer
membranes, some of the first to be made for consumers.Some would crack, some
apparently have minute shorts tripping keys in a ghostly manner!

Quite some time ago, these were in the news, but I noticed this
morning that these are being blamed for small shorts on Cassini now.
With the ISS being life extended etc, i wonder how long it will be
before we hear about hese here. I find it odd that according to the
Cassini story, they are still not really sure why these occur. Its
definitely something one will need to stop if we want to live on other
planets I'd suggest. Do they only occur in microgravity, or is it some
interaction due to radiation and free radicals or maybe ionised gas.

back when I was still working, we were having a real issue with
Silver Migration in the touch pad control panel membranes

takes a while for some issues to come to the forefront.
