I have observed a change in behavior when launching applications via URL Protocol. Ignition Gateway: 8.3.6 Client session A: Windows 11, Perspective Workstation 8.3.3, Tab/Window Links 'System Browser' Client session B: Windows 11, Perspective Workstation 8.3.5, Tab/Window Links 'System Browser' I have a link object in perspective; url: "myapp:", target: tab. A registry key is configured to launch Myapp when myapp: is called from Run or a web browser. In session A this launch's myapp with no further prompt. In session B the webbrowser opens with a blank tab, myapp does not launch. I have confirmed this functions on the same PC with 8.3.3 then breaks once upgraded to 8.3.5 and 8.3.6 ---

If the link is sent not to open a new tab then it does function but you get a prompt, where as previously if new tab was selected it would just launch ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/2/a207ef626dda087c10e831e908d60a66db467bfe.png)
