File Open/Save dialogs don't show up when I run Bryce 5.01 on my Intel MacBook Pro (under Mac OS X Tiger).  It's like they are hidden underneath the main window (I say this because I can catch brief peeks at them if I switch apps using Command-Tab, although I still cannot make use of the dialogs in this way).  I can still open Bryce scenes by double-clicking them in the Finder, but I cannot specify file save locations from within Bryce (for example), which is the real problem.  Has anyone else encountered this problem and/or found a solution for it?
