sorry, got tied up on other things.
after more investigation, I'm seeing hundreds of black windows from files that have been deleted out of any folder I go to.
occasionally there might be a thumbnail but when I try to open it, it is either very small or blank.
I don't see this problem when view folders on the desktop or across the network from other macs, seems to be only from our servers.
I have been able to select the file and delete them, but that really shouldn't be the solution.
Sorry I can't tell more about our server configuration, I asked my IT folks to look into, they seem stumped.
any other thoughts?
