5.12b doesn't keep where you quit
After loading 5.11, I found that its impossible to navigate through links in Hyperlink mode, so I found that 5.12b fixes it.
But I've found that this version doesn't keep the position where you quit reading. In fact, when I open a file it's always at the point where I left it before loading 5.12b.
Thanks in advance.
Table page layout
It could be that the document is using full page table layout, in which case, the saved location is the top of the table you are currently viewing. Try disabling table layout to see if it helps. While viewing the document, you can do this by going to Menu/Edit/Options/Content and changing the Layout setting to "Disable Table Layout".
I've checked it again, disabling table layout (even if the text doesn't have any table inside), and the problem persisted. Then I've tried with other files, and... it works fine!
I think that the problem must be in wherever it saves the information, because I've deleted the file, loaded it again, and when I open it, it's always at the same point! Is there any way to fix it? (it seems this happens only with this file).
