Link to external site in storyline opening in same window

I have found that you need to use the browser window next to the link and change it from "default" to one of the options in the drop-down.  Who knew the "default" doesn't do what you think it would. For us, it just makes our course (regardless of the browser) drop to the bottom tray and hide itself.  Changing it to either "full screen" or a "custom size" will allow the course window to stay open behind the thing you have open up.  There are course browser choices in the "player" but there are browser choices for each link too.  See images. I only figured this out yesterday after 3 years or more of this issue and telling learners to check their bottom tray browser windows.  I hope this helps you or someone else...for those who have never solved it yet (I saw lots of threads) and those who run into it in the future.
