i know its not good practice but a client requirement...
in our web application we want to prevent back and refresh functionality ...
we use custom window without any menu, address bar links etc... so no one entere through from here.
we handle all shortcut keys as we well...
we stop context menu to pop up ....
but requirement changes and now the context menu pop up but with only one or two options for example properties menu option is required for some cases and on other cases we want to give our custom option in this context menu...
how to do that to work with IE, Fire fox etc....
