I have always had hope for the 3.x series of MT-Newswatcher. So it was quite cool that it went from 3.1 to 3.5.x series recently. Why did I quit using it way back when? OH YES, because it always inevitably trashes it Preferences files or corrupts its own database.....

Muti Threading is the coolest thing (definitely missing from Thoth).
But everytime I revert to MT-NW, it will ALWAYS end up corrupting itself, thru all iterations, on every different Mac I have ever owned, throughout all the OS's too.

I hope they can address this fatal flaw, as otherwise, I will always look for the latest version, and want to encourage updating this app. Good Luck.
I am still going to give it 4 stars, because of the history of this app development
