thanks so much for responding
sadly, i have tried that. it has been of minimal help. IF multiple views derive from the same workbook it helps - a little (see next example)
this allows you to toggle back and forth without returning to the menu, but doesn't seem to allow both to be open in separate tabs at the same time - i.e. can't drag one to another screen so both can be seen.
in the Desktop development version they look like the following - i.e. completely separate tabs at the top where i can drag one to another screen.
so, even though i did check the multiple tabs option on publish, it does not give the options on tabs like the first example and overlays the tabs in the second example.
any more thoughts? i welcome all input.
