Hey there, Im using Thunderbird on a mac and want to open Thunderbird with another program (called EPIKUR). Its a software for my psychotherapy office. I can chose to write an email via thunderbird by clicking on a patients email. Thunderbird starts a window for writing a new email but as soon as i want to send it, Thunderbird crashes. According to the Epikur software support the settings in epikur are all ok. Any ideas how to fix the problem? Thanks Philipp
