I'm specifically asking for when the "Display HTML formatting" is configured as "As a table of the visible fields.", but I think all options behave the same way.
My users click the HTML Popup tool, click the feature on the map to display the HTML popup window, and resize the window until the get the desired size. If they close that window, and repeat the steps...the windows reverts back to the original size and they must resize each time. They feel, and I agree with them, that the window should open up to be the same size as when it was closed. Is this an ArcMap configuration? Or is there a registry value? Is there a way to affect window size if you format using an XSL template?
