Bug in 1.6.10 rule comments

[frankdr]

After setting comments on about 52 rules, the descriptions suddenly shifted so that they no longer are showing on the same rule they were previously. The comment on the rule I was working on moved up to the top and all the other comments shifted down one. Luckily I was able to exit without saving the change and reloaded and got back to where I was previously. I'm not sure if I can reprodcue it, but I'll see if it happens again.
