Thanks,
Yes it has occured to me this is possible, I believe my OS updated it's self a couple days ago during the night. It seems like best practice to get a fresh download anyway... that and re-install java.
I'm more worried about btfg being down. I can't access it from three different machines, and yet the pools list (which updates every 5 minutes) says there are active miners?
I'm quite sad to see it down and can't understand how or why I could/would have been blocked from pooling with them. A corrupt local wallet can't interfere with web browsers on three separate devices...
Have a great weekend,
M
