Is anyone else having problems with Thunderbird 5? If emails have attachments it is painfully slow to browse through the inbox because it is pausing for around ten - fifteen seconds on every damn email. Often triggering the "Mozilla Thuderbird is not responding" message.
Presumably it is invoking yet another virus check every time the email is viewed in the preview pane. I'm sure the old Thunderbird version (3) only used to virus check attachments when the email was downloaded, not every single time the email is subsequently previewed / viewed. I send and receive a lot of Word documents and consequently most of the emails in my inbox have doc attachments.
I've looked online and Thunderbird 5 slowness has been reported by lots of other people but apparently regarding the graphics rendering.
Any ideas how to sort this problem? At the moment I've either got to completely disable the virus scanner or switch to different email software. Thuderbird 5 is unusable. This is a great pity because I've used the various incarnations of Thunderbird for many years now.
