is virtuoso can create unique runtime space for each cxt

Hi,

Background inforamtion: we create a form GUI that restrict launch one only in a virtuoso seesion, and it creates a lot of global variables.

And now, client wants to launch multiple GUI in a virtuoso seesion, but our history code is too huge that we can not modify all the callbacks bind to their own widget.

So I want to ask a question that is there a way to create unique runtime space for a form or "cxt(contents file)" ?

or any other way to achieve this goal ?

Thanks,

James
