BUG
** This issue is addressed in ArcGIS 9.0 Service Pack 2 (SP2) **
A page that contains a Map control and some code to select a feature and to highlight it using CustomGraphics (in Page_load()) will execute correctly, but when zooming in or panning, the SelectionFeatures and the CustomGraphics are gone, if the page is executed using Server::Transfer(), even if you pass TRUE to preserve the FORM.
