>>Hi All,
>>
>> I have an application (VFP6.0 SP5) that uses a treeview and I want to select a node and drag it to another node that is off the screen. E.g I have to scroll up or down to reach the target node. The problem is that when I select the node to be moved and try to scroll up or down the treeview does not scroll. Does anyone have a solution for this?
