Bookmark ribbon not appearing when pushing bookmark icon

I am having the same issue, and it is happening with my copy of "Steve Jobs" I downloaded today...of all things to mess up on, is that spooky or what?

I Am having same issues with bookmarks and Steve Jobs. how can we get this fixed

I am having the same problem with several books including Jobs' biography. It seems that this problem always occurs in landscape orientation but if you turn the iPad 90 degrees to portrait mode it works ok.

I've noticed other problems in landscape mode such as pages appearing blank until you turn it to portrait mode, and text not highlighting properly in iOS 5 and iBooks.

Yes same problem. This started after i updated to OS 5

Ok i reinstalled ibooks and the bookmarks are working properly in portrait but not landscape mode

I have never seen a more problematic eBook on the iBookstore than (as someone said, ironically) the Steve Jobs bio. I mean, if you check the threads in this section, it's wall-to-wall complaints about some aspect of that book acting screwy. Poor Steve. Of all the books this had to happen to, it was the visionary who made it all possible.

OK, I have a theory about how this thing is behaving; bookmarks seem to show up/behave as you would expect (when I tap on the ribbon) provided I have the font size set to something that appears to paginate the book to its original (just a guess on my part) layout. If I increase the font size to make things larger/more easily readable, then things get screwy as described above as the pagination bumps up the # of pages and the page #s where a ribbon gets place doesn't seem to correspond to the exact visible page I wanted it on. Confused? So was I, but the evidence seems to point to this.

Anyway, try this out and see if it doesn' behave as I described.

Bottom line - iBooks does not behave in a rational manner and therefore it is buggy in my opinion - i.e. this is not a "feature"...

I have no experience with other iBooks downloads. Steve Jobs is my first purchase - and this this is my introduction to iPad and iBooks and terribly ironic to discover behavior like this with the ode to Steve book - which, BTW, I am enjoying max.

I think I've found out how to fix it. Apperently there is one font size that WILL NOT show bookmarks when you add them. For my Dracula book, its somewhere in the middle size fonts, but if make the size just one "degree" bigger or smaller, voilà bookmarks work perfectly. This worked for me, so give it a try. Also I've found out the there are different sized "not bookmarkable" for different Books, so go ahead and shrink/grow the font size. hope it works for you, cause reading is way too fun!!!

I've also noticed that switching from portrait to landscape and back again seems to fix it temporarily.

Still having this problem intermittently. It seems to come up every few chapters in the book I am reading.

Also I've run into a situation where after a certain page, all other pages are blank. It can be corrected by adjusting the font size but why should I have to adjust the font size every few hours of reading? That bug seems to accompany the bookmark bug.

Seems a bit more buggy than I'd expect from apple. Has anybody submitted an official bug report or has anybody heard whether these are known issues or not?
