Correcting myself, looking at the code what happens is that the  
compile script looks for a file with extension .pdfsync. If it finds  
it, then it tries to sync, and if not then it doesn't.

What this means is that currently, if there is a document on which  
you used the pdfsync package at some point, but then stopped using  
it, then the .pdfsync file is still around and the shell script gets  
confused. So a quick workaround, if this is the problem you are  
seeing, is to remove the file with extension .pdfsync.

We should probably change it so that it compares the modification  
date of the pdfsync file with the tex document, and if pdfsync is  
older then not sync. That still wouldn't be perfect, but would be an  
alternative.
The other alternative is to change the code so that it scans the  
appropriate documents looking to see if the pdfsync package is being  
loaded or not (I guess we could look at the log file for that  
probably, that might be the simplest solution).
