vista thumbnail flash and disapear??

i'm having a dilemma with a window vista workstation (dell precision t5500). when viewing thumbnail image off the server it will display all the thumbnails and half will flash and display the default image. on a win7, it doesnt do that. i've checked the tools > folder options > 
unchecked - always show icons, never thumbnails
checked - display file icon on thumbnails

anyone know why??? thanks in advance.
