Kevin,

The form that is working correctly has the following class definition:

public class AssetForm : dstBusinessForm

The form that is not working correcty looks like this:

public class FilterForm : dstBusinessForm, IdstFilterObjectHost

Could this definition cause a problem with the GetActiveForm method?

Thanks,

Mat

When I click the close button on one form's toolbar, the GetActiveForm method gets a reference to the correct form. When I click the same button on the second form, the GetActiveForm either gets null or a different form?
