Hi to all, I work as a system administrator (LAN +30 computers). I have been working with TB for a lot of years,sometimes I had some kind of problems or issues that I could manage in one or other manner. From version 91.XXX onwards I and having really important rendering problems, the program gets stuck all the time and it is almost impossible to work with it. This is happening in all the computers with diferent accounts, profiles .... It takes also a lot of time to download the email from the server ... what is really desperating ... You click in an email and starts a big pause what makes impossible working with it. I finally decided to unistall the latests versions from all the computers and block the updates. I am working fine with version 91. All the computers normally uses more than one account or even many profiles to be used by the different users. The account manages an important number of emails and they also spend an important amount of disk space (some of them with more than 20-30 GB). Anyway, note that I am also havong problems with not such big accounts If you need more detailed information that can help, let me know. Thanks in advance. Best Regards
