There are too many pages of replies for me to read and see if this has been suggested. If it works, I'll leave it to your integrity to give me the credits.
Try CRTL+ALT+DELETE>>Task Manager>>Processes
I use Firefox, so I go to "firefox.exe" and right click. Elevate the
process ("SET PROCESS" by right clicking on it) to "high" and confirm. Then go to "plugin-container.exe" with
the description of "Plugin Container for Firefox" and do the same thing.
ANY time I have had meter issues, this has fixed it. I usually try
to do it at the beginning of a round. You have to repeat it each time
you close and open the browser, which can be a pain, but TOTALLY worth
it. I gave up trying to close all the crap going on in the background
because a lot of it just opens back up.
Oh, and I use Norton, iTunes (which ALWAYS runs in the background), and I constantly have Outlook open.
You're welcome in advance!
