Hi!

Thanks for the reply.

It seems to be a bug but I think I found a work around.

If in my CommandButton1.Click event I SetFocus to the ListBox and then loop through and mark all items as selected and then click on the scrollbars of the ListBox it seems to be working ok.

*-- Start of CommandButton1.Click
Local lnCnt

With ThisForm.ListBox1
.SetFocus()
for lnCnt = 1 to .ListCount
.Selected(lnCnt) = .T.
next
Endwith
*-- End of CommandButton1.Click
