If I turn off / start / restart the system, all is fine.
If I select "sleep" instead of "turn off", the system goes to sleep as expected and wakes up from keyboard (did not try scheduled recording but it should be the same). Then, an error window shows up, named "Windows Script Host" and saying the fololowing:

Script:  C:\Program Files\Team MediaPortal\MediaPortal\restart.vbs
Line:    21
Char:    1
Error:    The system cannot find the file specified
Code:   80070002
Source: (null)

The only button available is OK, I press Enter and then MP goes to Home menu, not live tv as usual.
I select "My TV" and then MP gives me the "unable to start graph" error.
I cannot go past this whatever I do, I have to restart pc.
I can check tv guide and watch recorded shows, but not live tv !

After restart, as I said, it goes straight into live tv, same channel I watched last time, as it is supposed to do and everything is fine. Until I decide to try the "sleep" again, maybe it is working now... but it is not. Same behaviour on Hibernation. I used to t/shift on a RAM disk, but now it is back on HDD, this did not change anything. I am sure the sleep was working fine with RC2.

Any ideas, please?
