Ever since the latest update for poser 2014 every now and again all the thumbnails vanish from the library version Im using now isposer 2014  10.04.27796 .poser still works ok renders fine saves ok you can search ok and it finds everything but no thumbnail pics.This does not happen with version poser 2014 10.02.25578 I have both versions on my pc I keep the earlier version on my pc on seperate drive just in case things go wrong with the update and something stops working or older saves wont load (had that one before) so I am fairly sure the problem must lie in poser its self .Restarting poser will fix the problem for a while maybe a day or two maybe a few hours seems to be totaly random.closing just the library browser and reopening it is not enough to fix it poser must be fully closed down for it to come back working .this is the same for all categories even after a new search untill poser is restarted
