Thread.Sleep and Custom Filter

Hi all,

I just downloaded my eval copy today and started familiarizing myself with the application and ran into a situation that another user on the forum ran into previously with Thread.Sleep showing as a time consumer in functions, specifically when a function uses it, the time in sleep shows as time within a child function.

I would like to avoid including Thread.Sleep in my profile so that its data is not recorded, so I took a look at the custom filter thinking that I could filter out its contribution. One of the entries in the custom filter dialog in the "Do not profile .NET methods that start with" listbox is System. I am going under the assumption that that System value is not recursive down to the classes below System (Is that true?)

I then added the following lines:
System.Threading
System.Threading.Thread
System.Threading.Thread.Sleep

My problem is that I am still seeing Thread.Sleep show as a time consumer when I profile my application.

Now my questions are:
Am I using the custom filter in the correct manner?
Can I not filter out .NET System class members?

Thanks for any input,

Joe
