In A2010, I have a bound Form that is displayed as Continuous and is
set to be Popup. Its size has been set.

If I alter anything in this Form, e.g. just some its code, I find that
when I reopen it, its length is now greater, filling the whole
screen. Very maddening.

Since I prefer to use tabbed windows I have to change to overlapping
windows to be able to resize the Form. This means I have to go to the
File menu, Options, select Current database, check Overlapping
windows; and then resize. Quit and then reopen the database and
repeat the whole tedious list to get back to tabbed windows.

Is this a know fault? Or can one set the size of a popup window when
in tabbed windows?
