Thanks Martin and Stacho The latest development version e66c699 has resolved the issue. pdfTeX can now find surface images with ./ and ../ in the file path.

I'm tentatively thinking it only affects exports with surface images. Same thing occurs with two of them, and all the exports I have tried without surface images are fine so far. Here is the error that 5.5.1 produces. !pdfTeX error: pdftex.exe: cannot find image file ==> Fatal error occurred, no output PDF file produced! ##################### end of pdftex log file ##################### C:\Program Files (x86)\Therion\therion.exe: error -- pdftex exit code -- 1 writing xtherion file ... done Interesting, because the image file IS there, and if I install 5.5.0 an output is produced. Here is synopsis of what seems to be material differences in the log files. Looks like maybe the new version of MetaPost Is not parsing the surface image properly. Bruce
