Are you using AE 12.2.0?
Has this happened the whole time on this computer or was there a time that it worked? \
Does it happen with CS6?
Any chance you could test this with Windows 8 and not 8.1 or maybe try seeing if there's a Windows update? I remember when 8.1 was initially released, it had a number of problems (and was even killing the Surface tablets) and Microsoft pulled the update.
It has been happening sense I started.
I have not tried CS6. I am download it now to check it out.
I wish I could test it with windows 8, however I bought windows 8.1 OEM disc for my OS. So I don't think there is any way to go back. (should have just gotten 7...).
It is very possible this is an all windows 8/8.1 problem. This fourm is a similar issue that arises with the preview:
Let me know if anyone is having similar issues or has any ideas!
Update: CS6 has the same problem
