Running v49. When attempting to copy/paste an effect from one model to another, xlights crashed, as I tried to paste the effect. I restarted xlights and went right back to the same portion of the sequence; no further problems so far.... I tried to attach the debug report, but am not seeing one in my folders... (?)
Ok; self-inflicted. Accidentally hit ctrl-c instead of ctrl-v when trying to paste, so effectively trying to copy/paste blank cell... Got debug report this time; attached it. I'll try not to be so fat-fingered from now on.
