Either show the same form over and over, or make those variables static. Or perhaps store them in a seperate class that does it's own serialisation, and is a singleton, so all form instances can access the same data from there.
If you posted code, then I'd have made specific suggestions on how to change it. If the 'info' includes the state of controls, then only showing the same form over and over instead of creating new ones will do the trick, unless you also write code to save and restore those states.
