[OS X TeX] broken tex distribution

Felix,

I added a line of code in TeXShop to protect against out of bound  
errors for DefaultScript.

This preference should have values 100 = PdfTeX, 101 = TeX + DVI, or  
102 = Personal Script. When setting it using the Preference Panel, the  
value is picked up from a tag on a button. It is possible that this  
tag was incorrectly set in a past version of TeXShop (and if so,  
probably in one of the localized nibs)

This question is less interesting than it appears(!). It's a matter of  
tracing through the code which selects the typesetting engine, and  
watching what happens when an unexpected value of DefaultScript is used.

I have no idea.
