I'm using a free little utility called Rainbow Folders to customise some of my frequently-accessed folders, to make them easier to find. It works well on the folders themselves, but some of the shortcuts I have created from them are intermittent inasmuch as sometimes they show the colour I have used while at other times, they just appear white. This problem only occurs with shortcuts that point to folders on my Synology DiskStation. Is there any way I can troubleshoot this? It's not a big deal, but it would be nice to rectify if there were a simple solution.
