Go to the View->Use Progressive Disclosure menu of the display control and uncheck it. OK, I see - the View menu of the display control window. Yes that seems to work. Very convenient, I can imagine creating all my new displays with rubber banding, and then doing this unchecking of the ones I want to remain fixed. But currently this fixing doesn't work across saving and reloading of a bundle. The saved displays seem to have their UsePD status (yes/no) remembered correctly, but not their region. When I save and open a bundle, all the displays automatically open to cover the initial view. Even those whose display control View menus have Use PD checked off. Also, zooming or panning while the bundle is loading seems to make the view-matching displays come up with different coverages according to the moment they are created. Is that inevitable? Maybe we should always be patient and never touch the IDV while it is loading, but try telling that to students in a classroom with limited internet speed. Even displays that were created with UsePD unchecked in the main view window's Projections menu at their creation moment do this display matching upon save-open. This could be dangerous if the bundle is saved with a very zoomed-out view? -- oh except the stride parameters are adjusted too (AutoStride), so it is OK. So there seems to be no way to create displays that reliably cover fixed regions any more!? Oh - I found a way. I have to use the old-style region selector in the field selector. But even THAT fails if the UsePD checkbox happens to be checked on under the Projections menu at the creation moment. ------------------ Summary: The ONLY way now to create a display covering a fixed region is to BOTH uncheck the UsePD tickbox, AND ALSO not use the convenience of Match Display Region even though it is avaiolable with the tickbox unchecked. Every other case yields displays that all match the view when the bundle is opened. I hope this is a bug of .xidv saving and/or reloading, not the way things will always be. Brian
