Word 2007 crashes sometimes on exit

[latief75]

i upgraded to office 2007 after i got my new pc, a lot of my work documnets are in word 2003 format which i will not change for a while to assure compatibility....every now and then (like once a day) word 2007 crashes while i'm closing the application (after having one of my documnets open) ........and it tries to restore but cannot.........

any ideas ?

i'm running vista premium ,,,

thanks,
