Usually, avatar hands are "relaxed", and every so often when standing idle avatar hands will go into an open state with all fingers spread out. Sometimes only the left hand will be spread open and the right would close into a fist. I have noticed this being much worse over the past few weeks than it previously was. Playing an animation which closes the hands, (I usually just fly up and down with the default animations since the hands will close briefly) will usually correct this problem. However, a full re-log is sometimes needed before the hands will return to a normal relaxed state. Simply walking around often fixes this problem as well. It's not exactly a show stopper, but is still quite annoying, especially when this happens several times during photo sessions or similar. The viewer used doesn't seem to matter. I did see VWR-1793, but created a new issue as VWR-1793 seemed to be directed at new animation uploads rather than any animation, no matter how long it had been uploaded. They may be related though.
