>HarryT: maybe he can go back 1 version - I have not seen confirmation that 1.9 no longer works.
> my lost book issue: it occurred again today - new purchase downloaded then vanished, so I tried one of the simple earlier suggestions. I simply closed K4PC then re-opened it. Much to my surprise the new book was then present. that is good as it means the bug is less severe than I thought & I don't need to toggle registration to fix it.
