Dear filter specialists, On a Windows 10 computer with TB Portable 128.6 and .7, folders can no longer be selected in the filters as ‘Run filter on’ or ‘perform these Actions’: the menu is greyed out. The phenomenon occurs with all accounts: POP and local. Various email providers, ESET virus scanner, Windows firewall, FritzBox cable router. The local account contains almost 30 GB of emails. The existing filters work as long as they do not affect the accounts or folders: for example, tagging e-mails works. Existing filters with folder-actions cannot be re-configured and no folder actions are possible when creating a new filter. I have performed an update check and restarted Windows, changed the compression limit from 500 to 5 MB and changed a few minor settings so that the config is rewritten. What could this be? How do I solve the problem? A workaround if necessary. Thank you very much for your help.
