[texworks] external read-access causes TeXWorks to revert open file to old version

[Stefan Müller]

Hi,

it has been a while since the last reply, but I was only now able to 
test again on my Linux machine with those debug messages you gave me (I 
didn't compile it for Windows).

So, still strange things that happen. (Sometimes) When I change 
something in the open tex file in TW, save and commit this change with 
TortoiseHG (my Mercurial client), the debug messages say that the open 
tex file has changed and that the same file is loaded (again). Then TW 
displays an older version of the tex file. To get my current file back I 
have to reopen TW.

So there are basically two possiblities I can think of.
(1) TW has a problem with TortoiseHG accessing the tex file and 
"restores" an old version of the file. What goes wrong? Where does the 
old file come from?
(2) TortoiseHG messes with the tex file causing TW to reload it. Why 
should TortoiseHG write on the file? And if TortoiseHG temporarily 
writes to the tex file, why doesn't TW reloads again when TortoiseHG 
restores the current (committed) version?

Hopefully someone has an idea what's causing the problem or how it could 
be fixed, especially if it's (1). Thanks in advance.

Best regards,
Stefan
