There is some bug in the book wizard that occasionally causes an error message when you try to save. I get an automatic error report when this happens and I have seen it happen to a couple of you. I made some changes today that I hope will cure the problem and I improved the error reports so I can learn more about what is happening if not.

My current theory is that it is related to saving your book after a picture search that has not yet completely finished updating all the little preview pictures, perhaps because of network slowness. If you see this problem, wait about 15 seconds or so for things to settle down and try saving again.

Also, as always when using computers, the best advice is to save early and often.

I apologize for the difficulty this has caused some of you.
