Dead Keys are not dead, they are just annoying.
I bought a Slide-Arch E-Blue keyboard, I like it small. Few keys behaved oddly. I thought that could be a driver issue as I found a driver for it when installed it at home on XP.
It wasn’t about driver. I tested it again and again with other keyboards they all behaved the same. So I turned to the hardware and thought that it might be something else.
I never have to worry about typing diacritics because we use simple English during the day. Too bad I selected
English – US keyboard US – International as input language hence this problem.
