In general, new accounts are difficult to set up, and it is impossible to do anything, especially, having multiple accounts till every new mail has been downloaded. Just annoyingly slow.
I have kept 126.96.36.199 till yesterday, but gave it up since Secunia PSI kept bugging that it was not secure.
So, I am relying on TB 3.1.10, and it opens with an Alert. That the "folder" is being processed, and to press OK to proceed. Only then, downloads proceed. Typically, I can get to minor accounts, as each one becomes available after downloading its new mail. It may take up to five minutes before I can access all accounts.
Is anyone else getting the Alert?
