Hi again,
Paul, Keith, please update and let us know if the problem persists.
No such luck at this end: I checked out release 8773, which looks like the patched version. But then replaying the check_open sequence from above while pointing at the new binary gives me:
[the file "fred.pdf" is in both "~/Desktop/testing" and "~/Desktop/testing2", but only the former version is open in TeXShop; and it's the only file open in TeXShop]
% cd Desktop/testing % /Library/Application\ Support/TextMate/Bundles/Latex.tmbundle/Support/bin/check_open TeXShop fred.pdf %
[That is, it correctly reports that the file is open. Now just change dir and see if it thinks the other pdf file is open too...]
% cd ../testing2 % /Library/Application\ Support/TextMate/Bundles/Latex.tmbundle/Support/bin/check_open TeXShop fred.pdf %
[the output from check_open isn't distinguishing between the two. Can anyone else verify that this behaviour is persisting?]
Cheers, Paul
