Not sure what happened... I moved to a new machine, downloaded a new version. Exported settings on old one, imported fine. Then today I went to do an Action and notiiced they weren't there. No biggie, I can rewrite them.
So I enter the one I use all the time to remove the / from a track number... Then click the checkbox to apply that action. It scans thru the files, and says 0 of 7 tags affected. OK, I must've mistyped something. Go into Actions again - and the Dialog box is empty! It never saved my action, so never applied it (I assume).
