Hello...
This is just a guess based on the trace and your comments about the
problem occuring on 10,2,8, but it looks like your PSMPreviewView's
initWithFrame: implementation is calling some other method that does
not exist prior to 10.3.
You might want to go through your implementation of the
initWithFrame: method and check the documentation for all the methods
you call within that method to ensure that they weren't added in 10.3
Panther. The name of the offending method is probably also being
logged to the console when the crash occurs, if you have access to
machine running 10.2.8 or can't find the problem by checking the
documentation and need to ask your users to check for you.
You could also (if you haven't already) compile against the SDK for
10.2.x, which should result in warnings for the offending method
call, although that way of testing your code for older OS versions is
far from foolproof.

Hope that helps,

Hi all-
I am puzzled by the behavior of my shareware for some (but not all)
of my users who have upgraded to the most recent release. The app
includes a new custom view I have written (PSMPreviewView) and
crashes immediately at launch with the following crashlog:
Thread 0 Crashed:
#0 0x97e54964 in _NSRaiseError
#1 0x97e547ec in +[NSException raise:format:]
#2 0x97e00ba4 in -[NSObject(NSForwardInvocation) forward::]
#3 0x9068c130 in _objc_msgForward
#4 0x000134a4 in -[PSMPreviewView initWithFrame:]
#5 0x930fdb50 in -[NSCustomView nibInstantiate]
...
