@skid, not sure if this would help, do you send the WM_SETREDRAW message to the treeview.
one note though i recall reading that microsoft confirmed this to be a bug!
SYMPTOMS!
If a program uses the WM_SETREDRAW message to turn off updating of a TreeView control before adding items, the TreeView control can behave strangely.
For example, if the item being added to the control uses the TVI_FIRST style to insert it to the top of the tree and the top of the tree is scrolled above the top of the visible window, it may be impossible to bring the item into view.
Another possible symptom is that the TreeView control doesn't repaint itself at all. These problems occur only if the program has used the WM_SETREDRAW message to turn off updating the TreeView control.
could this be the cause of the refreshing problem?
