i am having trouble getting a jQuery  jqwidget app working for one specific customer.  its as if the underlying jQuery is being blocked somehow.  This simple example is only using a jQuery drop-down combo-window.

we tested it on Edge, Firefox, and Chrome on two separate computers.   and right-click on the element does not show any console errors.

it behaves as if either the router or cox-cable at this particular location is somehow "blocking" the left-click to work!  

my next guess is to have the client try a VPN, but i wanted to solicit some other expert opinions.
