It's odd, chmou or quintela never asked me for results before and after, so

I as I said earlier a plain 2.4.20 kernel seemed to fix the problem too, I
never ran any tests though. Will this qualify for an updated kernel for 9.0?
BTW. Where am I supposed to file a bugreport?, not here or in bugzilla because
it's only cooker related. At mandrake expert you need an account? Do I need
to _buy_ support before I can do this now?
Chears.
