I'm having a problem getting Context to work properly I'm having a kind of weird problem with the Context module in my Drupal 7 environment.  I have the module installed and enabled, however, when I go to Structure --> Context --> Add, the Add Context Admin UI appears and under "Conditions" whenever I select one of the choices, the box to the right of it does not activate like it should, so I cannot put in a path or whatever.  Nothing at all happens.  It's the exact same for the "Reactions" as well.  

It works fine in my development environment and the environment with the problem was migrated from the development environment, so I don't understand why it won't work.

I have tried completely uninstalling the module (including deleting the 'Context' folder from the server) and re-downloading and re-installing, flushing the caches, etc.  Everything I can think of and I still get the problem.

Is this a problem anyone else has seen and how do I fix it?

Thanks
I had the same problem with the "blocks" section.

In the blocks section, you need to select the block(s) you want to add in a template region from the right panel where there is a list of all the blocks. Then click the + sign of the corresponding region.

As for the condition problem, that is weird have you tried in different browser?
