Is SMTP4DEV 2.09 compatible with Windows 7?

Jan 10 at 1:23 PM
I have been running 2.09 on Windows 10 without problems. My colleague downloaded and installed it on her W7 machine using the same instructions that I had just followed and started it running, with exactly the same option settings as myself. When she sent test SMTP emails, she got a message "smtp4dev has stopped working" and a message from Visual Studio Just-In-Time debugger "An unhandled reception ("System.ArguentNullException") occured in Smtp4dev.exe [10696]".
