Hello, We use Thunderbird for our work e-mail from someone contracted out to us. We do not want to have to restart everything as we has e-mails we can't have deleted. It has been very slow when clicking on emails takes 15-30 seconds for it to load. In the windows bar thing it says not responding then it will come up after 15-30 seconds. When when writing this takes awhile for it to respond, it is pretty much with every click. Any help would be great. Thanks
