I encounter this quite a bit in solutions where I do actually want to allow the user to use the Layouts pop-up menu to navigate between layouts. The problem, to which I'm sure you're referring, is that at certain times you DON'T want to allow the user to switch to a different layout, but you DO want the status bar and its controls.
One good solution is to use the OnLayoutExit layout script trigger (FMP 11 or 12)
For instance, in a recent solution I built, I have a "Leave Layout Control" script that is called by the OnLayoutExit trigger in some layouts.
If( $$allow_leave_layout = 1 or $$disable_triggers = 1
Exit Script [result = 1]
Exit Script [result = 0]
by setting the boolean value of either of these global variables, I set the exit script result that permists or prohibits the exit layout action from completing.
this will not hide the layout bar but as you just don't want the users to be able to jump to layouts through the drop down list try this; File>Manage>Layouts and for each layout you wish to omit from the list deselect 'Include in the menu layout', hope this helps.
Thanks Erik..will consider this
Thanks..yes thats what I have done for now..cheers
