"Please, add only one file at a time" message

Hey buddy,
I love this plugin. Got a question: are users supposed to receive “Please, add only one file at a time” message when they try to upload a file after successfully uploading a file?

My users have to leave the BuddyDrive add new file area to upload two successive files. If that’s not normal behavior do you have any ideas what’s wrong? If that’s the way it was designed are there plans to allow this going forward?

Thanks in advance for your help.
