Can't close Mbed-Studio V1.4 on win10

Can’t close Mbed Studio V1.4 on win10.
I can close Mbed Studio V1.2 and V1.3 very well.

Hi @wubaojun,

Can you tell us more about this issue? Do you see any notification when you try to close Studio?
The only thing that comes to my mind is when you have an auto-save disabled and you have at least one file unsaved. Mbed Studio should then warn you that it can’t be closed.
