With Version 3.96 this didn't work

Please try to reproduce this and let me know, what's the problem...

In Versions up to 3.95z if I press 'Alt' + '0' I can drop a bookmark, as I can see in the Status line. With 'Alt' + 'J' '0' I can jump to the previously assigned bookmark.
Anyway, if I press 'Alt' + 'J' the new bookmark dialog was opened, but there are no entries.
Furthermore I hope that I can get an update to 3.96 for free because I bought the 3.95z only 3 weeks before the 3.96 was launched.
I cannot get bookmarks to work at all.
