There used to be a popup that would state "Loading" and disabled the ticket page. This is not present in the OSticket Awesome version that we have. This enables the user to hit the "Create Ticket" button several times. Each time that the button is hit, it creates a ticket. If it takes longer than a few seconds, most users are hitting it again causing several duplicate tickets in our system. 
I haven't run into this but it sounds frustrating. I will look into it.
I was just able to recreate this in the demo system on your site. I think that if there was a way to re-enable the loading pop-up, it would take care of this issue.
@jschrader@myios.com,
Thank you for taking the time to report this and to look into it further.
Your suggestion is likely valid. I do not recall disabling the loading popup, but perhaps it got accidentally disabled through some other change.
Unfortunately, I cannot honestly say that I will have the time to look into this for the next week or two. But it is on my list!
Do you know where the loading page would be in the php or css files? I have a development system that I can play around with.
