OK so far. I noticed it opened in an existing lister, so tried adding NEW to the GO command:GO NEW "\\GARY\David\Susan\Audio"
but that didn't work, so tried putting NEW at the end and that worked:GO "\\GARY\David\Susan\Audio" NEW
Then tried to add Set AUTOSIZECOLUMNS which works by itself on a separate button I made, but doesn't work altogether as part of the single command:GO "\\GARY\David\Susan\Audio" NEW
Set VIEWFILTER *.mp3
Set AUTOSIZECOLUMNS
Not sure why this doesn't work. Do I need some sort of delay before doing Set AUTOSIZECOLUMNS?
