I have a similar question in regards to imported LOR stuff. Two years I did my arches in xlights then imported the effects into my LMS files. ...and the USB hard drive on which I put those files died on me.... So there you go. Anyway, I need to tweak on some of my imported stuff (want to delete actually)---it seems like when I block out rows & columns of nodes, I can delete some but not others. Is there a "smarter" way to do this? Baffled here.... THANKS
