Hi Chris , I'll install the new version later today.
I started to get all kinds of weird stuff happening, at one point Drive C disappeared from Explorer, which was a bit perplexing - as that's the OS drive....
So I bit the bullet and did a full Windows reset. It gave a list of the apps uninstalled, so I go through that step by step and see if anything starts to misbehave.
Will keep you updated, thanks for all your help - and patience
