We use the Mere Mortals framework. Somehow one of our forms is running into the following problems:

The form is marked to allow multiple instances (and to number the forms). Open the form the first time -- no problem.

Close it and reopen it again and it crashes. It somehow thinks a session number is being saved in ln session. In the Osession.init of the application class (the application is "just2", the application class is the "just2" class created with it) it tries to set datasesssion to lnSession. Since lnSession does not exist it crashes.

Any easy answer as to what property I've set wrong or omitted?

Thanks
