Python IDLE Autocomplete and Call Tips No Longer Pop Up

Question

I recently upgraded to Python 2.7.10 on MacOSX Yosemite. I also added a Python 3.4.3 installation. At the time I upgraded Tcl/Tk with ActiveTcl 8.5.18 as was suggested on the Python for MacOSX installation page. There is also an ActiveTcl 8.6 package from last year that still shows up in the framework, but I was pretty sure that I said to delete that when I went back to an earlier version of 8.5. Path has settings for all three as well as usr/bin, etc.

At this point, Autocomplete and Call Tips stopped popping up. I checked the preferences and it seemed to be turned on. The delay was set to 2000, so I changed that to 2, but nothing happened. Pressing {ctrl}-Spacebar and then using the down arrow key lets me cycle through the the available functions, but putting a dot after an object has no effect, and if I open parentheses, I get no tips. This is both in the IDLE Shell and Editor windows.

I tried to redo everything by deleting all instances of Python from my drive. I reinstalled them, reloaded all packages, and Autocomplete and Call Tips still are not popping up. Is there any known issues or is there a workaround? Do I possibly need to add or change the new Tk path somewhere so that IDLE can find what it needs to popup autocomplete? Is there a way that I can initiate IDLE Autocomplete and Call Tips during the coding session to manually get them to work?

I have also raised this with ActiveState and Python, but I haven't gotten or found an answer yet that has gotten it to work. I like working with IDLE and would like to get Autocomplete and Call Tips up and running again.

Thank you.
