Thanks for the reply. I'm still a python and TG noob so I'm not sure how to complete this upgrade of just the json-py part. The json-py-3_4.zip file (from sourceforge) doesn't contain a setup.py file. Installing it manually in my site-packages isn't enough (TG is still using the egg one). What else to I have to modify (manually) to get to use the 3.4 version of json-py?
I really appreciate the help. I very much want to use TG but I'm getting stuck on this MySQL/json-py int vs. long int problem. Evan
