Hi Doru,
Glad you were able to debug my code. I can't type more than a few lines without making an error. I did try to run it tonight, and found the problems you mentioned. As to the form that won't die, I don't think it is related to the Example object, but you can be sure with a test: just get a reference to the form (I usually do the ON KEY LABEL F12 o = SYS(1270) thing, then press F12 with the mouse cursor over the form's caption), type o.CallMeObject= .NULL., then see if the private session's gone (SET) and see if the form closes properly. I tried it and it worked OK. I would expect, as you, that some objects have a reference to the form, or an object on the form has a reference to another object on the form.
Christof Lange's explanation of DataSessions was very helpful to me. http://fox.wikis.com/wc.dll?Wiki~DataSession~VFP An object is bound to the current datasession when it was born. This allows you to design visual classes with a private session; just instantiate them in a session.

this.CallMeObject = NEWOBJECT("Example", "CallMe.prg")

this.value = thisform.CallMeObject.callme(thisform.txtEmpID.value)

>After I exit the form, something like a ghost form object is left “alive” – I can see it in the Locals window in Debugger – it has no properties or methods. I guess the thisform.release that executes on the Exit button click() fails because some other objects still exist at the time??
