While I think this subject is beyond the levelof the average"user" I am a bit reluctant to move it yet to the Installer category as not everyone would have access to it ie the original poster.Guys like I said it is obviously a bug in 2.69 and asking for a fix here is probably not going to get you anywhere if the manufacturer has not been able to fix or reproduce it yet.While I appreciate the problems this is causing your best course of action at this point is to deal direct with Samsung if you are a dealer or your distributor.That is where you should direct your energy and put the pressure on to escalate a solution.I'm sure when a fix comes out someone will post it here,until then downgrade the system software if you can.
