Drop-down menu doesn't open (but it worked fine some time ago)

Hi!

Thanks for the extension, I use it heavily. On Zimbra mail service's web-client there is a drop-down menu called "Move to..." where you can choose folder where the letter currently open has be moved to. It worked well some time ago, but now doesn't. How can I check where the changes are what changed this?

Thanks in advance.

You could be seeing this: #2257.

Oh, I'm sorry for the duplicate, if so. This can be closed, then?

Thanks.
