To all of you who responded to my original plea, Thanks! I have discovered what the reason is for the error message, how to correct it and the clue came from scifiguy (thanks). The reason for the message (which is the wrong error message) is when one downloads an object for Poser all the files have to be put into the approriate folders for the model to work properly. This varies by the way the author created it. I usually never read the accompanying "read me" files, but I did in one case and the author left instructions where to put the correct files. As I said, some are different and loading many into Poser folders can be very tedious. Now I read all the "read me" files. The problem with the Poser "memory" error message is that it is erroneous. The code should have been be written to reflect the true nature of the error. I have a friend who always tells me to "read the book", but guys aren't supposed to read instuctions; well, let this be a lesson to me. Thanks to all again.
