I have written an MDI application in C# under VS2010.
When I drag the thumb on the vertical scroll bar, the window does not move until the thumb is released.
Research has turned-up some things, but none of the information I have found so far has worked.
Does someone have some guidance on this issue? I want the window to scroll as I drag the thumb.

Set the Scroll Bar Property ScrollTrack = True
Edit:
Check the last example here: http://www.pcreview.co.uk/forums/determine-scrolling-mdi-form-mdiclient-t1323005.html its related to detecting scrolls to repaint child forms to avoid flickering
And please have a look what Hans Passant does here: Issue Related to Scrollbar in MDI Form in C#
psuedo code:
protected override void WndProc(ref Message m)
{
try
{
switch (m.Msg)
{
//Scolling progress and Completion will be triggered
case WM_HSCROLL:
case WM_VSCROLL:
//this doesn't work
//this.VerticalScroll.Value = x;
//I haven't tested this but it should definately work:
