After updating to 4.12.1 (we are on patch 8 from San Diego), the Studio application no longer works.
When we want to "add an existing file" in Studio, the pop-up still loads and nothing appears.

As a solution we recommend to use $j in scrips instead of top.$j .
In order to use Angular or JQuery in custom scripts, you will need to import it into the script or into a Global UI Script to make it available to all client scripts.
If the UI script snd_xplore_glasses is disabled, the Studio App works correctly.
