When I first updated to Win XP Home it ran flawlessly. I now frequently get an error dialogue box labeled "mmc.exe - Application Error". The box reads: "The instruction at "0x77f516c5" referenced memory at "0x008e0010". The memory could not be "read". Click on OK to terminate the program."

I click the "OK" button, the error message goes away & not much else seems to happen! Any way to correct/eliminate this annoying error message?
