Weird UI issue: When hitting BILL on a Sales Order, the users have to hit BILL 3,4 times before the button reacts. This happens across different browsers, and in intermittent across different users too. Any ideas? cleared cache/Incognito mode Tried different browsers different machines

check any client side scripts and user event scripts for anything executing. client side first and then user event.

It seems as if something is occuring from the moment the button is selected before it finally actions something. Is it the same behaviour in UAT or Sandbox? Is the network okay?
