Error 1172 when click on Processes tab in SimpleTaskMonitor.vi

Question

Hi,
I'm trying to run the SimpleTaskMonitor .net example that comes with LabVIEW 7.0. When I click on the Processes tab while the vi is running I get the following error:
Error 1172 occurred at Exception has been thrown by the target of an invocation.>> Cannot read Instance :CSDispatcher. in SimpleTaskMonitor.vi Possible Reason(s): A .NET exception occurred.
How do I fix this problem?
I have Microsoft .NET Framework 1.1, Microsoft .NET Framework Hotfix (KB886903) and Microsoft .NET Framework SDK (English) 1.1 installed and am using LabVIEW 7.0.
I had been getting a message when I opened the vi that the System, Version 1.0.3300.0 assembly had not been referenced, but I found a link on NI's website that said to double-click the PerformanceCounter constructor nodes in the vi and select the appropriate constructors from System, Version 1.0.5000.0. I did that, which made the message when I open the vi go away, but I still get the above error when I go to the Processes tab while the vi is running.
Thank you for your assistance!!

For those that might be interested, we've been able to isolate it down to a Win32 issue and CSDispatcher. Using a straight C# application, we get
Received an exception: System.InvalidOperationException: Cannot read Instance : CSDispatcher.
at System.Diagnostics.CounterDefinitionSample.GetInstanceValue(String instanceName)
at System.Diagnostics.PerformanceCounter.NextSample()
at System.Diagnostics.PerformanceCounter.NextValue()
when trying to read the "Private Bytes" value. I am not sure if it is a bug with the Win32 Perfmon provider or something that CSDispatcher has done to disable that counter.
