1.4.2 pdflatex viewing problem

[chipbrock]

On a mac, OSX 10.4.2:  I have just upgraded lyx to 1.4.2, replacing  
everywhere the installer said "replace"...Now, I cannot view a  
document in the pdf viewer. If I do View->DVI, the file happily  
appears through my default tex viewer (TexShop). When I hit View- 
>pdflatex...I get the error: No Information for viewing PDF  
(pdflatex). I notice that much is different in the format preference  
and gather that some of the pdflatex stuff in the new version of lyx  
is changed?

Any ideas? I've never had any lyx problems before this! Thanks...
