That's much better, it doesn't crash anymore, but the look is not quite 
good. See in the first attached capture what the example in 
multi-pane-view looks like. Seems to me like the top and bottom lines of 
the tab view are reversed.

More important, this is not the standard tab aspect in OS X 10.5. You 
can see in the second capture what they look like in one of the System 
Preferences panes. Any chance to make it look that way? I don't know if 
that look is available in Carbon though. Here's the HIG page that talks 
about it:
