I've experienced this too (with a similar software setup) -- not at  
all consistently, but just enough times to find it annoying. Glad to  
hear it's not just me!

I don't think this used to happen, but am unsure whether the key  
change was upgrading from TeXShop 1.x -> 2 or from Panther -> Tiger.  
Can't imagine that the gwTeX setup is a factor.

Have you tried viewing the PDF with Preview at that point, to see  
whether the new input really was typeset, and the problem is only  
that the TeXShop preview didn't get updated? Or viewing the source on  
disk with another program, to see if it was saved? I must confess I  
haven't investigated properly at this point, but there are things  
that could be checked.

Could it be something subtle in the Cocoa framework, like Save  
operations completing asynchronously, so there's a possibility that  
the typesetting job starts before the save is completed, and gets the  
old version of the input?
