[texworks] "jump to source" not working 0.3r736

[Duncan Murdoch]

I've just installed the test build TeXworks-w32-v0.3r736-build1.zip on a 
64 bit Windows 7 machine.  The "Jump to Source" menu item on the right 
mouse button in the previewer appears to do nothing; "Jump to PDF" in 
the editor brings the previewer to the front, but doesn't go to the 
right page.

I suspect this is due to problems reading the .synctex file, but I don't 
know how to diagnose what they are.  Version 0.1 r432 is fine with the 
file.  (The reason I suspect problems is that the .synctex file is a 
little unusual:  it is not compressed, and it has been edited from the 
original one produced by pdflatex.  So it is possible that the edits 
have messed it up, but I don't know how.)

I have put most of the example files online at 
http://www.stats.uwo.ca/faculty/murdoch/temp/texworks.  (There are 
missing figures, but the main source files are there.)  The .Rnw file is 
the real source; jumps should almost all go to it.  The .tex file is an 
intermediate file produced by Sweave.
