Quote - You can have external binary morph targets off but enable file compression, that should reduce the size of the saved files.

I don't use either file compression or the binary morphs... makes for big files and slow loads.. but I can open close, re-open, create new for many hours without crashes... only when I work with either compressed or binary morphs do I get crashes on opening a new file or going into the material room.

If I want to work on a file previously saved with the binary morphs I save it as a new name (so the fill is guaranteed to be written again to disk). I will then close and reopen Poser and continue... Why the close and reopen? I too have had crashes after opening an previously saved "binary format" file... My guess is that when the file loads into memory it is over writing something it shouldn't be (bad pointer reference?)... so when I open the material room or close the file and open a new one or a different one Poser melts.

Instead of a crash every 30 minutes or so, now I am getting one crash in a 3 - 4 hour session.
