I had today in the same afternoon 2 cpu spikes like I reported on older versions, I had to kill the DF process, always happen when watching video on WMP12 on windows 7 and with tittle buton enabeled, the move to the next monitor tittle buton.

I will desable the tittle buton feature and test further.

Next I attach my debug log file

If anything happen later I will repor it here.

I was just watching some tv show episode on WMP and then starts to video lag (I have an old P4 CPU), and I check on the Task manager and was DF on 24-48% load so I kill DF process and all came to normal, I start it again, and few hours later same happend. I came here to report, I desable the tittle buttons and nothing happens in those almost 2 days I enable it again and I will wait to see if happend again.
