Version 2 came out at the same time as my last trip to Australia. I
used it to set tasks and it seemed fine. Even uploading flight logs to
compare them with the day's forecast looked accurate.
I noticed something like that in the San Joaquin Valley for a while.
Too-regular lines that didn't seem to move much hour to hour or even
day to day, while the Sierra Nevada and Mojave Desert seemed fine.
There were a couple of other glitches with version 2 which I fed
back information on. Chris took care of those things quickly.
Contact Chris (info (at) xcskies.com) with your specific questions,
including the location where you're finding this problem. He's quite
responsive.
