Thanks Jeff - I just went in and made the droplets again inside Compressor (still have the presets) - gives the option to replace existing file, so did that and bingo back they went with proper icon.
Weird behaviour?!
Was worried that Motion5 was going to cause some problems but sits fine with Motion4 and the rest of FCS3.
Thanks - Martin.
