Hi, Sarah. I had a rocky time getting my app object working, too, but it finally is and was worth the pain :-). I have some questions though about your posting.

Does OnStart.prg do a form?

When the form releases, it sets the oApp.NextTask to a form name? If so, in which method?

Are your forms SCXs or classes? If classes, where do you createObject?

Is DO (oApp.NextTask) a prg? or a form? I assume prg...Your syntax works for me for forms...i.e. DO FORM (CFORM)

At what line/method do you get the error about instantiating the class? From your example, the only class I see is clApp...

>I just discovered oApp and that's the only change I've made to my program. I tested each bit I added to my custom class by going into my initial form and they are all fine - UNTIL I try to move from that form to another form. Then I get an error instantiating object. last time I got this I had a typo lurking but I can't find any. For a while yesterday the problem was intermittent but couldn't find what changed!
