My excel has been acting weird lately. All dropdown menu disappears quickly before you can even choose your choices. This happens in Data Filter function. When you press the grey triangular button to pull the options down, the options does show but after a few seconds it will disappear making it difficult to Filter properly.

I tried my file in ohter excel programs in other desktop and is running smoothly. It is only in my desktop that excel is acting different.

I don't recall changing anything in my excel option or setup.
