SYMPTOMS
If you add any non-ODBC counter together with any ODBC counter in Performance Monitor (PerfMon), you do not see any activity for the ODBC Counters.



CAUSE
This is a bug in ODBC Driver Manager. When any non-ODBC counter is present in the list, the Driver Manager does not send any data back to Performance Monitor.
