Maclean? I don't get any squares of anything in my thumbnails in Cameras. They look identical to the thumbnails in any other library. Correct Reference is the solution to stop Poser from locking libraries, yes, but I've had other locking problems with PBoost on WinXP Home with NTFS with Poser CLOSED. Sometimes I can't switch banks at all so had to stop using it. I run CR on everything in Poser but, as I said, even with Poser not running sometimes I couldn't switch banks.
