Topics suddenly opening in new browser tabs?

[Joel9991]

Hi all, I am hoping this is just a setting I accidentally checked or a new "feature" but suddenly today when I generated a new responsive HTML5 output in RH2019, it generated fine but any topic I click on in the TOC opens in a new browser window instead of the main help window as it did previously.

I have checked all over for something that would account for this, but cannot find something similar to "open help topic in new window" checkbox.

I have checked:

Project Settings

Preferences

CSS

Master Pages

Responsive HTML5 Settings

It does this in Chrome, Firefox, and Edge.

Anyone know what I need to do to change this back to opening in the same help window?

Thanks!

Joel

I've had the same problem, but I don't always know what I did that fixed it.

Eliminating drag and drop links?

Fixing a mismatch somewhere?

Usually publishing the parent project fixes (or causes) the problem momentarily and then publishing the child project fixes (or breaks) the system again.

Once I find the mismatch and fix/publish the issue goes away...?

Also, I starting to realize that use of RH Server probably helps to overcome some issues...
