It seems this problem has been there for a while. I have this problem in ADE 2.0 and 3.0. I solve this problem on my computer today.
This problem is not a "turnning page" problem but an UI refresh problem, if you turn page, close ADE and reopen it, you will find the page actually turnned, I guess this problem occurs on a computer which have two display card. On my laptop, a NVIDIA, and an integrated. ADE works fine on NVIDIA and not on the integrated one.
So Here is my solution: Tell ADE not running on the integrated display card but on NVIDIA. You can do so by using NVIDIA's control panel program. "manage 3D settings" -> "program setting" tab, add ADE, and tell it running on NVIDIA.
System: Windows 7; graphics (onboard Motherboard) Intel(R) HD Graphics 4600 Properties.
I have the same problem:
ADE does not turn page *unless* I resize the ADE window after turning the page. After resizing the ADE window, the page will turn.
I don't have multiple displays. I don't know how to adjust my display setting to facilitate ADE. Still looking for a solution... If you find a solution or a better product, let us know.
4 years later this is still an issue. Changing pages in ADE doesn't seem to have any affect until you resize the window, that will trigger it to redraw. Having to resize the window after every page turn is far from optimal.
