Hi,

We use the callback filter (.net 4.0) in our application and everytime we exit the appilication we get an exception "CbFlt.ECBFltError: The operation completed successfully".

We create an instance off the filter at the beginning and at the end we call the detach method and dispose methods, and those 2 result in the exception.

The stacktrace is the following:
Code
   CbFlt3Net.dll!CbFlt.CallbackFilter.DetachFilterInternal(bool Wait)   Unknown
   CbFlt3Net.dll!CbFlt.CallbackFilter.DetachFilter()   Unknown

Try to dispose filter instance after the OnFilterDetached event raise, or alternatively, use DetachFilterEx(True) in order to wait of callback mechanism termination.

If I use that method I recieve an other exception.

Code
A first chance exception of type 'CbFlt.ECBFltError' occurred in CbFlt3Net.dll

Additional information: An attempt was made to reference a token that does not exist


Same stacktrace

When I click that link, I don't see my issue.
Instead I see the option to create a new ticket. Do I do this?
