New Post: Can't get more than two multi-threaded filter streams to run

Well it looks like a bug with Tweetinvi then. I will investigate and get back to you.
In the meantime could you please upgrade to the latest version (0.9.9.6), there has been few changes to the webrequests.

I don't think this will fix the issue but it is worth a try.

Feel free to up vote the work item (https://tweetinvi.codeplex.com/workitem/2644) to get live notification about changes.

Cheers,
Linvi
