Ok, to be more specific it is when browsing with the explorer inside an office applikation that takes time.... everytime I doubleclick a folder to open it it goes many many seconds ...it feels like it is hanging for a while.... but when the office applikation got hold of the file it goes fast again ....opening the document itself takes 1-2 seconds...... it is the browsing for files inside the office that is my problem .... I'll download the system from sysinternals.... thanks /Johan
