************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true"
/>
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

Accepted. Need to set up test environment with Windows 2000 box and .NET .NET
Framework Version 2.0.50727.42

Must look closely at:

PerformanceMonitor.getDisk()
PerfMonG.PerfMonG.TimeTrigger(Object sender, EventArgs args)

I found the issue:

1. Go to Control Panel
2. Administrative Tools
3. Performance
4. Click on the + icon to add a new counter
5. Look through the items listed in the "Performance Object" box

You will note that:

1. Windows 2000 does not have an object labeled LogicalDisk
2. Windows XP has it

PerfMonG obtains the total amount of free disk space from the LogicalDisk 
object - or
Category. Since it doesn't exist on Windows 2000 it doesn't seem to be possible 
to
obtain the Total free disk space.

Suggested courses of action is to disable this feature in Windows 2000.

Easiest fix:

1. catch the exception in the getDisk() method in PerformanceMonitor.
2. set the value of the counter to some flag value (like -1)
3. detect the flag value in the GUI and set the display counter to N/A

This will be fixed in 0.2.6 but I will try to release a patch for the interested
parties today or tomorrow when I get a chance to fix the code and recompile.

Here is a patch for Windows 2000. This is an immediate release, untested, use 
at your
own risk, yadda, yadda, etc...

*PerfMonG 0.2.6-rc*

How to use this thing:

1. download the PerfMonG.exe file
2. drop it into Program Files\PerfMonG
3. overwriting the file that is already there
4. run PerfMonG and enjoy
