Drawings hanging system up upon checkout

Help!!!!! Something is causing our design platforms / systemto be running super slow. It's most obvious when selecting(clicking) a Solidworks drawing to open or check out. Suddenlythis tiny task is taking 15minutes or longer. It used to be instantaneous. We justrecently upgraded to the 64 bit 2009 platform from 2007 32 bit. Weused the uninstall approach and installed 2009 as if it were a newinstallation.
