I've been using Kompozer in windows for many years without problem. Finally loaded it in Mint19.2 with SNAP. Works fine with local files but when I go to access an external disk, it doesn't show up on front page of open file. Tried opening file directly but use "other application" does not show Kompozer. Can't get into "media" - permission denied. Can't changes permissions because ROOT only even though I am root. Could move files into a local directory but hope there is an easier way. thanks
