New Paltalk
The "Multi-Window Mode seems to be the one that is most user friendly to those of us who are used to the Classic version of Paltalk.   The Multi-Window Mode splits apart the interface so that your pal list and pms as well as each room you are in appear in separate boxes.  See below the example screen shot taken from paltalk.com. 
To access the Multi-Window Mode go to the General Settings in setup/preferences.  Click on the little settings icon just to the lower right of where you see your own nickname (above the pal list area).
Now click on 'general' on the left side of the setttings window.
You can make the text bigger or smaller in any window by using the Zoom Text feature in any chat or room window.

When in a chat room or IM on the far right click the button with three bars and you can zoom the text there.
If there is a problem you are still having with the new version of Paltalk, please let us know and we will do all we can to help you.
