Hi Terry, I managed to find the problem! As you suggested, I installed newer version of tk/8.5.15. Then, the same test will still fail, but the error message has content now. It complains about missing font. I did some google, then fix it by installing "dejavu-sans-fonts".
I laughed when I found the problem, and indeed, this small bug has bothered me for a whole day. Thanks again for your help. I would probably spend hours and days before even think about trying newer version tk. :) Best, Kai On Wed, May 21, 2014 at 1:55 PM, Kai Song <ks...@lbl.gov> wrote: > Hi Terry, > > Thanks for your reply! > > >> Nasty.
