I can confirm new 1.10.5 v.1.0 the loading notification is gone.  I keep getting duplicate tickets from end users clicking "create ticket" more than once.

Has there been any update on this?

Truthfully, I am still struggling with this one.

I understand what the issue is but I haven't figured out a resolution (yet).

I am working very hard to get some new releases for 1.11.x out the door and then this will become my top priority to resolve.

Thank you for your patience on this guys.

We just recently updated to 1.11 so we are do not have this implemented at the moment. 

If you're interested, I just released osTicket-Awesome-1.11-v1.0.
