Thanks for the advice. I did a fresh install of KDE 5 last night and didn't really have time to mess around with Adept. I've been using regular Mint for a while and it's my first foray into the Mint KDE world. Does Adept have a history of being kinda flaky compared to Synaptic? Reason I'm asking is that I did a fresh burn & install of KDE because Adept kept crashing. Never, ever had that problem with regular Mint (Daryna forward) using Synaptic.
Just because I'm in that kind of mood, I may do an install of XFCE and see how that goes. Funny thing is, I've done such before and ended up back in GNOME -- I guess I never learn!
Thanks again & think kindly on the U.S. -- we need all the good karma we can get right now!
