@shaggy thanks for the advise, i am careful about any stress on the screen ever since it happened (btw it was only a cell phone placed in that area that caused it, very sensitive indeed)
@modsRule I use the continuous scrolling when I absolutely have to but it's weird doesn't feel natural, I really like the flipbar.
On a side note, soon after posting here I discovered
PDFCropperX which is really awesome. I just make 2 cropboxes, one for the top half and another for the bottom, this essentially splits the page into two pages. I can than add about 2 inches to the top by printing it on a larger page size. Now I can use the flipbar
