Admin Panel is Unresponsive

Has anyone noticed that (perhaps since WP 3.4) that their admin panel for Gravity Forms has lost a lot of functionality?

For instance, I cannot go to "Entries", and then navigate through forms using the top-left pulldown.

I am unable to "trash" entries, and a myriad of small features.

Nothing terribly important seems to be broken, but it does seem like every non-critical button is broken.

David,

I havn't had time to create a testing environment and go through the testing process. I will do so when I have the opportunity. I really just wanted to see if anyone else in the community is having similar problems.

In general terms, nothing happens! No visible errors reported, or white screens etc. Essentially, if I try to filter "Entries" by a specific form, the page simply doesnt filter results. Or if I attempt to "trash" a response, the page reloads, but the entry still remains.

It does not seem to be browser related, as Chrome, Firefox and Safari are all demonstrating the issues. Tells me this is related to my site, either through the plugin, plugin conflicts, or something to do with my organization.

I'll report back to you when I can do proper troubleshooting.
