Tom,

>The application I am working on has three forms based on cBizObjModalForm. Two of them no longer work correctly. They each have an exit button the executes thisform.release(). Now the objects of the form are released, but not the form itself. If it is useful information, the modal form that still works correctly is called from another form, while the the other two are directly called form the menu.>

It sounds as if you have a "dangling" object reference in these forms. In the Mere Mortals Developer's Guide, check out the topic "Application Forms Not Releasing" in the section "Handling Application Run-time Errors".
