illustrator menu flash open when clicked and them immediately close

[Shadows and Light]

When trying to open any on screen panels or icons etc they open and immediately close automatically making them totally useless and i cannot change any values. This does not happen in any other program i.e. photoshop lightroom etc. 

Not sure if there is a setting i can change. I have tried re-enstalling illustrator but the problem remains.

Any advise please.
