Rick,
The frameserver takes "screenshots" of JMRI windows. So if the window has been reduced, that's what you get a screenshot of. One item of note, the window can be minimized and still work with the frameserver. So if you're not using the same windows on the server, resize them (on the server) to remove the scrollbars, then minimize them. Give that a try.
Sounds like you're trying to use the panelserver on your older iPads, which isn't going to work. The clearest way to distinguish them is via the path (in the address bar of your browser), if it includes /frame/ or /panel/. Examples using my demo layout:?panelserver: ?vs. frameserver:?
To get a list of frames for your iPads, use this path:?http://jmri.mstevetodd.com:1080/frame/ This is the page displayed via the "List" link at the bottom of frameserver pages.
Note that the "Home" page links to panels use the panelserver link. Not the same as the "List" link.
