Something has been preventing me from using ctrl+z at in everything. Ctrl and z are working fine separately can use as undo option in anywhere in my window. I am running Window 8.1 and it occurred just a few days ago.
The Ctrl+z is working fine in safe mode though.
Can someone tell me how to fix this problem.
Without ctrl+z, life is really hard. Every time I have to click the undo button manually.
Thank you in advance.
