Thanks for this very useful tool, great job.

Strange GUI

On my dev linux vm I have the issue that the FakeSMTP GUI shows me only the Menu, but I can't see the controls and e-mail list, thats very strange.
From my point it must be some system/os/virtualisation related thing that blocks the gui.

Thanks for analyse and help in advance.
