Hi Long-term Thunderbird user and in the past couple of months Thunderbird on my PC on connecting to my mail server goes to a time out (about a minute?) before then downloading new messages. Connecting from my laptop is instant. The PC - which is relatively new - performs well otherwise. Checked settings on both and they are identical, save for the laptop.being 64-bit and the PC 32-bit versions. Any ideas for me to try? Many thanks Rick
