Okay, so not a TDE thing! Good to know. The MX is currently a complete clean
install as I haven't migrated anything over to it yet (just fyi). I'll make
backups and futz with the schemes and also search/ask on the MX forum. Ah,
yeah, dumb me, I'll check the "XFCE desktop" MX installs by default too,
which I should have done before posting :(
When I get a definitive outcome I'll post back here.
Best,
Michael
