Occasionally, new versions of operating systems take us by surprise by 
introducing new conflicts, incompatibilities, or bugs while running 
Mathematica.  That's what has happened here.  MacOS X 10.2 causes several 
issues with the Mathematica user interface which did not occur in previous 
versions of MacOS X.

Your crashing problem is the worst of them, but there are a couple of 
other serious ones.  As somebody else pointed out few days ago, text 
copied from Cocoa applications (like Mail) does not paste correctly into 
Mathematica.  This, also, is a problem newly introduced in 10.2.

We're working on a patch right now, which will be freely available to 
anybody with a licensed copy of Mathematica 4.2 for MacOS X, and will fix 
all of the 10.2 issues we're aware of.  I'll make an announcement on this 
forum when it's available.

In the mean time, there is a workaround for the crashing problem.  The 
most common occurrence of the crashing problem occurs as a result of using 
Command+D to press the "Don't save" button of the "Do you want to save 
changes in this notebook" dialog.  Until the patch is available, you can 
avoid this particular cause of the crash by using the mouse to click the 
"Don't save" button instead.
