Opening linked document in new window

It is most useful to have a master rich text with links to various pdfs for consultation. The links work well in the same window. However, opening in a new window (which is more pratical) using the alt-command-click combination does not always work. Why is it so?

What kind of link did you click, e.g. an automatically added link (see preferences), an Internet link or a link to another document you’ve created on your own?

These were links that I made up from a central document to its annexes. Thanks for looking into this.

I’ve found a minor issue in the current version if one releases the modifier keys before releasing the mouse button. Maybe that is responsible for the problem? In that case the next release will fix this.
