Well, the reason for this behavior is that when teh mouse moves over the button: it is a scenario of Form1_MouseLeave for the Form.
The Form considers that the mouse has left focus from myself(Form). Since, now teh focus is on button and not form.

One simple way to solve this could be to write the below mentioned codeon the MouseEnter events for the button and label also:

And, similarlly for label also.

After a bit of thinking, here, comes my simpleand smart :) solution:

Add that event for a button(button1) and then-
Add the following code in your Form's constructor:

The code is self explanatory. Would be glad to know if it works for your requirement.

There is another problem atleast when i ran the code. If the mouse moves out of the client area of the form i.e. if i move the mouse to the title bar it changes the opacity again.

            this.Opacity = 1;
        }

        private void Form1_MouseLeave(object sender, EventArgs e)
        {
            this.Opacity = 0.5;
        }

There is another problem atleast when i ran the code. If the mouse moves out of the client area of the form i.e. if i move the mouse to the title bar it changes the opacity again.

I used the code below for the testing purpose which had both the events set.

        private void Form1_MouseEnter(object sender, EventArgs e)

        {

            this.Opacity = 1;

        }



        private void Form1_MouseLeave(object sender, EventArgs e)

        {

            this.Opacity = 0.5;

        }
