I have done a policy as follows:

screen saver = enable
screen saver executable name = I have inserted the path where is the file "xxx.scr"
password protect the screen saver = enable
screen saver timeout = enable I have inserted 10 min.

When arrives a notify of groupwise it awaken the PC , and the pc doesn't go into screen-saver?

How can I revolve this problem?

For now I have reduced the timeout of screen-saver , but it 's a workaround.

Please can someone give me suggestions?
