Upload button gone when trying to upload images

After the recent update, the interface for uploading images and such is missing the blue Upload button, forcing me to use the Enter key. This is much more annoying that I thought as I rarely use the keyboard when hanging out with people, and having to adjust my position and do an extra thing every time I want to show something really adds up to frustration in the long run.
Please let us have the mouse-clickable Upload button back when sharing images and so on.
