I find that if I click on bookmarks on the igHome bar then it gives me very old bookmarks which seem to date from when I had the Google toolbar installed. I find it a bit worrying that they have appeared as I had no idea they were being recorded. Google bookmarks faq - a bit old.
I am totally cofused now as I have just dicovered that google bookmarks are not compatible with google chrome bookmarks. (whatever that means! )
but if you have any further info in the future please let me know.
