No No It's Not Just Ducky! ME TOO!
Hold it, it's not just Ducky or theDucks.
This has happened to me repeatedly since yesterday when I downloaded 0.21, in fact last night when I was trying to get my &^%$#@ to validate on epub 1.05, I had to go back and make a crapload of changes, and they just don't...for lack of a better word, STICK. I have this problem repeatedly on S&R- if I make a change and close the s&r box, and, heavens forbid, change the view to WYSIWYG, the changes in cdodeview disappear and are not saved.
It is particularly egregious on s&r, although I have had it happen with manual changes, also. I made some s&r changes last night, saved it, ran the validator, and, kablammo!--same errors. Went back, looked, and the changes had quite simply "undone." It's like using CTRL-Z on a global basis.
@Ducky, you ain't alone, and @Valloric, it isn't something he's doing, at least, not uniquely.
I am running XP 32-bit.
