Ok, you asked:
what are you file uploads settings on forum – options – content settings? do you have the option to constrain popup turned on?
The settings were:
Thumbnail width of images in posts (Minimum 100px): 100Default image style:left
This of course results in thumbnails, and the popups that are big enough where the top of the image is behind the WP admin bar have their X hidden/inaccessible.
SOLUTION/WORKAROUND:
I’ve unchecked these boxes, and I am getting a better result for my purposes because the images go into the post at full size, constrained/scaled for the forum width. As a result, there isn’t a need to click on a thumbnail & enlarge, so there is nothing to conflict with the Admin Bar.
Whew, long way around to get to this point. Sorry this has been so much effort and thanks for all of the work on it!
