Looking for free Big5 Chinese viewer that runs on Win7

Hi,
      I am looking for a freeware (on Windows) to read Big5 .txt novels.  IE can open and display the files, but the long text lines won't wrap around and is real annoying (if someone knows how to set max line width, that should work too).  MS Word can open small .txt files, but the larger ones (few megabytes) seemed to take forever.  I tried and came back after ten minutes and it was still opening the file!  
Thank you very much in advance.
