>>Hi,
>>
>>I have a form to which I add several container objects or remove existing container objects. When the form is resized the current existing objects will be re-arranged in order to show as many as possible horizontally without needing to scroll and then moving down the form if more space is required. i.e. a vertical scroll bar will become added as more objects are added. Sometimes objects can be removed from the form.

>>Generally this works as required. However, sometimes when the form is resized or objects added/removed VFP suddenly displays a black area on the form from a random point downwards to the bottom of the form. This whole area is just black. Resizing the form, which triggers the resize event, re-displays the form objects properly again. Any idea what this black area is and how to prevent it occuring?

Thank you. Running thisform.draw after adding/removing all objects works fine.
