Upgraded to JIRA v6.4.1 yesterday - today cannot add watchers to issues

Question

Is anyone else seeing problems with adding / viewing watchers in JIRA v6.4.* ?  Worked like a charm until we did the latest upgrade. Now it's flakey.  Sometimes when you click the number of watchers nothing happens, other times it pops up the list of watchers and allows you to add or delete (as it should).  This is not a permissions issue.  They haven't changed.  And it's working/not-working in the same project.

We have same problem on JIRA 6.4.3.

Did someone already created issue for Atlassian?

Does anyone else have the "JIRA Watcher field" plug in that allows you to add watchers on issue creation?  We are experiencing the same issue, but have that plug in, so I cannot help but feel it is related.

We just upgraded to 6.4.3 and are having the same issue.  We can add watchers from the More drop down but not from the Watchers field directly.
