We found a bug in the 1.4 release: "objc" was not importable in Python, and this was causing problems with PyRAF's interactive graphics. We have released Ureka 1.4.1 with a fix for this problem.
If you have already downloaded 1.4 and are experiencing this problem, there is an easy work-around:
- locate and open $UR_DIR/python/lib/python2.7/site-packages/PyObjC.pth in your text editor
- change PyObjC.pth to say "./PyObjC", and save the file
