When I open Thunderbird V. 52.9.1 (32-bit) in the morning to check my mail, I will read an email then try to delete it. My Thunderbird then doesn't respond until I restart the program. It takes between 10-15 minuets for the program to actually respond in deleting any of my mail files. I have tried everything I have found on Thunderbird not responding or not deleting and the problem still persists. Please if anyone knows anything that would help, all will be appreciated.
