Thanks to all who responded..... I posted this when I was quite frustrated trying to play a round. So to clarify a few things:
1. I always reboot my computer and clear my cache before playing WGT.
2. I have had the same system / mouse / etc for over a year with issues only occurring randomly.
3. What I find hard to explain is how it played fine on Saturday, then horrible meter on Sunday.
4. I will try a new wired mouse, and Maxthon browser to see if any change.
5. I had tried different browsers and definitely saw remarkable differences in game play ability and in more areas than the swing meter. Several were just plan unplayable (Firefox)
I've seen the other threads about the issue and surprised how nasty they all become. Aren't we all just trying to play a game and help each other achieve that?
Thanks again for the suggestions!
Tom
