I go to edit a Page Builder page. When I go into the dialog box to Select Image (screenshot below), the button to Media doesn't do anything. When it does work, it will go to the dialog box to add an image to the site's images folders. And that works sometimes works and sometimes it doesn't. It's almost like I have to clear cookies or release a thread by backing all the way back out of the template editor, back to the list of T4 Page Builder - Pages (screenshot below). Then when I try again, all goes well. This is very frustrating. Is this a known issue or is something else? Where are these images when I select them? Is there a way to streamline this so I can shortcut my image selection? What directory are the images really being stored in so I can upload them via ftp first?

Thanks for any guidance in this.

It works correctly for one or maybe two times, and then it doesn't work unless you go completely out of that process, back to the main screen for T4 Page Builder. What I was asking was, is there a way to use ftp to move images into the first screen for "Select Images"? I can select a new image in this screen all the time, but the Media button doesn't work all the time. Is that possible?
