Thanks!
Great explanation!
I was not expecting the visible property to prevent a form from releasing.

>In the click event of the close button on "frmMyFormClass" place

thisform.visible = .f.

At this point the code will continue in the calling form and you can dispose of oForm

Local oForms as form
>oForm=newobject('frmMyFormClass','myClassLibrary.vcx')
>oForm.Show(1)
>* oForm is modal at this point
>* User clicked Close button which caused "frmMyFormClass" to loose focus
>* Control resumes here when oform looses focus by being made invisible
>oForm = .null.  && Force oform destroy
>release loform  && release oForm

>>Why won't this form release?
>>
>>Have a form class in a vcx with a close button with 'release thisform' or 'thisform.release()' in the click method.
>>
>>In another form have a button with this in the click method:
>>

>>local oForm
>>oForm=newobject('frmMyFormClass','myClassLibrary.vcx')
>>oForm.show(1)
>>

>>Clicking on the close button on the myFormClass form does not release the form! I have to click on the 'X' in the titlebar to close the form. Why is that? If this is unstandard code, how would I lauch a form that exists only as a class?
