Solidworks flashes model veiws when Autocad opens

Ever since I upgraded to sw2009 I have had a conflict with Autocad2004. When Autocad starts up, solidworks will begin flashing all of the models of the current open assembly. Each model will be displayed in about 2 or 3 different rotated views for about 1/2 second each. Once all of the models of the assembly have been displayed, it goes back to idle and I can continue working with Autocad. See attached avi. Has anyone seen this before? Thanks.SolidworksParts And Features
