Threads - how to stop multiple new windows opening

[petergo]

hi there,

I am running the latest version of TB, and win 10 pro.

Lately, I have noticed, when an email contains several replies or threads, when I click on it, all the emails in the message open in new windows.

I have worked through View/Threads and tried each choice to see if I can stop this happening, and I even looked through settings to see if there was an option, but I have been unsuccessful so far to resolve this irritating ( for me ) action.

Appreciate any advice
kindest thanks
cheers
peter
