Thanks, maacruz. BTW, since I installed DT I have twice gotten the situation where it won't dim and the power button fails to work. I know that this is discussed in this thread -- I apologize that I haven't grasped all the details or the current status of the problem. This is not a big problem for me because I can just reboot using the advanced power monitor and the problem goes away. But please let me know if there is anything I can do to troubleshoot the problem. Also, if I figure out any pattern for what triggers the behavior I will of course post here.
