Quote - also - my library in Poser Pro 2014 keeps losing the ability to display pngs after a few hours of use, I restart poser and it's fine.

I get something similar: After some hours of work my PP2014 takes 10-20 seconds for the thumbnails to eventually appear when I change/open a folder or category. It keeps displaying ones it already displayed, and the problem only happens with some (not all) folders/categories, mostly with those I hadn't used for a long time (or not yet in that session). Looks like a thumbnail caching problem, like if the library eventually "forgets" some unused thumbnails and has to rescan the affected folders all over again; Or, if it scans thumbnails on the fly, some really marked sluggishness in doing so.

As I said, for me waiting 10-20 seconds brings them back, so it's just a minor annoyance.

 

(64-bit Poser Pro 2014 build 10.0.3.26510 on Win7Pro, single runtime of around 200 GB. Runtime is inside Poser (old style), and Poser is on its own partition (not on C:). Flash and Air are kept up to date.)
