Just out of curiosity here, but for those of you who have been affected by this, what kind of system are you running on?  And what version of Bryce are you using?  I had quite a few problems when I started using Bryce, but nothing as major as that.  Just some things that require me to restore Bryce to defaults every now and then, such as not being able to alter object textures.  The first time was when I was trying it out, and it confused a lot of people here.  Bryster, and Agent Smith probably remember me for that alone.  And a few others who I can't remember.  I have Bryce on another pc, and on that one it never does this, just on my laptop, which I affectionately call Lappy 356. 

I remember reading something about Bryce not using the Dual Core system too well?  And the newer versions were to address that problem?  I'm not a programmer, but I am a system tech by training and experience.  When a bug does happen more than once, and to more than one person, there is normally a common point. 

The only problem is that with all of the different system specs for computers these days, actually knowing what that common point is, and being able to specify it, well that could take a team of techs with multiple systems a lot of time to run down every possible problem, or a lot of  detailed user feedback.
