>Sorry! My fault. In Help it says 'Window menu icon' but it really means this small little 'x' in the form title bar. When i click it, it changes the color to grey and nothing happens. The form is not released. The 'Cancel'-button on my form works. I am releasing some arrays in the release method of the form. One has an object refernce. I know from this mighty Gurus in UT that i have to get rid of object references. But they almost never tell you WHERE to do something. I also put this code into the unload method of the form (and tried some other foolish places). No change. So that leaves me with the question: what is behind this damned 'x' ?

Stefan,

It sounds like you have what's called a "dangling object reference". If an object is created in a form and not properly released, you'll see this type of behavior. For example, if you create a public object in the form's Init, the form won't release until that object is.
