A seguinte solução (de esta postagem no blog ) trabalhou para mim:
I am using Microsoft Mobile Mouse 6000 and the zoom function (by using CTRL + Scroll) did not work normally. What I did to overcome this problem is:
- Open Control Panel -> Mouse
- Select Wheel tab, then select Identify programs that don't scroll correctly... -> Click Add -> Browse for Microsoft Word -> Click OK -> OK.
- Now, come back to Ms Word, it will work perfectly.
