i was searching for "how to disble the menu bar" and found the quick solution to right click on the bar and uncheck the "Navigation" to hide the menu bar.
once hidden i couldnt find a way to unhide it.
thats when i found your question.
after a few clicks here and there, i found this solution
which works on my application
Right click on any sheet (not on any object, some plae where there are no objects) --> Customize toolbar --> Toolbar --> check the Navigation, to get back the Menu Bar,
hope this works for you as well,,,
Ignore the above reply.But how it can done for all the users(Automated way) and if some of the user preference has to be enabled at all user level. How this can be achived. Since we could find if you enable some settings in the Qlikview client-User preference and still it is not updated in the menu user preference resulting in unexpected output... Any suggestions.
