I have the same problem and this is driving me crazy now...
I use Office 2010 and I never had this problem until I went to Windows 10.
I’ve noticed I have problems with my cursor in other apps (such as Cubase or Vegas Pro) where the cursor is supposed to change
when hoovering a special area, a bit like in word.
The cursor also doesn’t display as it should when my mouse is positioned at the top left or right of the page.
One thing that may count: I have one 4k screen and two other standard monitors (I used exactly the same hardware on Seven)
I’ve tried several things and these two following temporarily solved the problem:
- - Setting
a custom scaling (105%)
- - Updating
my graphic card driver
For each of these two solutions, the problem disappeared but reappeared right after.

Sadly, It seems that Microsoft won’t pay attention to the problem under a certain number of people complaining.
