@ Analog-X   .....  it's not a problem to save or find default,  what Fran and I were perplexed about is you only get your default scene on start up, not when starting a new project from bryce already running. 

@ Fran...      LOL,   I know the feeling.  But I've got all my project in on master folder and subgrouped within that.  My AAA default is in master folder  so it is easily found.
