I have been having an issue with facebook recently. Even though on initial install I had it download all of my friends and it did so completely, whenever I go to send a message/write on someones wall/pull up my friends list, it says 99% Updating list... and it just sits there, and while it's "updating" the application then goes slow and lags, but meanwhile it just sits at 99% updating list. I also believe it is wasting battery power in the background when doing this.
Has anyone else experienced this and figured out how to get it to stop doing this?
