Getting simple browser applications to open in XOJO?

I’m a new user, working my way through “Introduction to Programming with XOJO”. In any of the projects that involve building a simple browser, I find that when I run my project, my “WebPage” opens up in my default web browser, Opera.

Presumably, to get the project to open in the simple browser that I’m “building”, instead of in Opera, I need to make some changes to my system. Can anyone tell me what changes are required?

I don’t want to change my default browser, but even if I were willing to do that, I wouldn’t know what to change it to.

I’m running Windows 10.

let it launch in opera and then point your browser at that url.
