I am using the code from this MSDN article

http://msdn2.microsoft.com/en-us/library/bz33kx67.aspx

Everything worked great on my single core CPU laptop. I then tried to
run the .exe on my Dual core Pentium-D at work. The UI becomes
unresponsive while the background thread is running. When I go into
task manager and change the CPU affinity from 0,1 to just 0, the UI
becomes responsive again. Please keep in mind that made the loop longer
so that I have time to observe the blocking. Anyone have any ideas?

Thanks

What does the memory consumption look like on the dual core box. You
said you made the loop longer to observe the blocking. Perhaps it's
working so quickly that it chews all your memory up?

Just throwing ideas out there.

I made a multi-threading async app on a dual core box with no problems.
The child threads would update a listbox with updates as they complete
certain tasks in text files. worked like a charm. thats why this is
kind of weird.

I had to put a Thread.Sleep(1) inside the Background Thread's loop.
Everything worked then.

Thanks

Please post a complete sample that illustrates the issue, there must be
something wrong with your code.
