The shell script CompileTeX-engine that Sneep's scripts call to do the real work make use of a number of osascript constructions, and it seems likely that one of those is the culprit. I can see how, in principle, how it might be happening (example below) but I can't see any errors in those osascript calls. (By the way, CFURLGetFSRef appears to be deprecated as of Mavericks.)

Thanks Michael!

I saw similar explanations googling, but I am not savvy enough to fix Maarten's script.

Interestingly, if the .tex file has an error the script points to the error line/s, but no "CFURLGetFSRef" message appears.

My guess is that when no tex error appears the pdf file is opened bringing up the "CFURLGetFSRef" message. However, once it has been tex compiled with no errors,  opening the pdf file from the tex source with the script does not produce the messaage.

Finally, I cannot see why being deprecated it is used by (the presumably recent version of) osascript anyway.

Oh well... as long as it works...

Thanks again.
