pc freezes after facebook and msn messenger

[El]

This new machine keeps freezing and having to be turned off at the mains whenever mega uses facebook or msn 
it doesn`t happen to himself or to me mainly cos we don`t use them but whenever she goes on them , we can`t log off or anything and it just stalls . It got so bad when she was on that she used my account instead of hers and the bloody same thing happened again 
how come  surely a new one should cope with messenger and facebook

El your not alone http://www.vistax64.com/vista-general/136480-facebook-crashing.html solution seemed to work here

[El]

ta Mike , have just done the solution so we shall see what happens when madam goes on it again
btw. it happens whenever it is i.e or firefox 

have told her I will ban bloody facebook and msn altogether if it happens again

Seems as if it is yet another Vista problem
