Tungsten T5 Promblems w/ last view location

[BigAl]

I have iSilo 4.15 on my Tungsten T5. I have all my ebooks on my Lexar 1GB SD card.
Everything works fine except "last view location". When ever I open up iSilo it brings me back to the beginning of the book, it can't remember where I was when I close it or go to another application.
Has anyone had this problem? Is there a fix or work around.
iSilo works great and it is a joy reading in the larger screen. Less scrolling.
Thank you....

Does the document use tables?

Try disabling table layout for one of the documents to see if it helps. To do this, go to the Options menu, tap Display, set the Layout option to Disable table layout, then tap OK.

The doc. doesn't use tables. But one of my other forums I asked the same questions and one person w/ a T5 said he had the same problem but it went away when he went back to 4.01. I tried to go back to 4.01 and it seemed ok until I tried to open a book and then I would get a fatel error and have to reset.
I decided to go back to 4.15 and low and behold the problem is gone and iSilo got its memory back.
I use Silver screen 3.3 to launch all my applications from and occasionally iSilo will not launch so then I close out Silver Screen and then reopen it and iSilo works again.
