I tried running it a few years ago (it was a recent-ish 4.x version), but it crashed - so I chose The Bat! instead. The crash bug seems to be fixed by the way, but I'm happy with my current choice (which is Pandora Mail).

I'll probably try Pegasus Mail 5 anyway. :-)

It has not changed much over the course of the past few years: https://windows-cdn.softpedia.com/screenshots/Pegasus-Mail_1...

From a UI perspective, I see no need to change anything from that screenshot. Glad he doesn't feel the need to fiddle with it.

MDI is a big bonus!

wow it has been ages since I last saw MDI based apps.

One of the reasons why I use Pandora Mail, honestly.
