Custom view crashes app for some

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::]

#13 0x00009324 in _start (crt.c:267)
#14 0x8fe19154 in _dyld_start

The people who have written are both using 10.2.8, but I cannot say this is universal. The PSMPreviewView object does respond to initWithFrame: , but does not explicitly declare it in its header; it is a subclass to NSBox and overrides the superclass' method. Add'l info: nib is Pre 10.2 format; I have seen in previous posts where this might be an issue.

I am really stumped; can someone provide any insight as to why most people's machines are fine with this new view, but others crash on launch? Thanks so much for any help offered!

John
