After button click

 

Hello,

when i create a button with the new MT4 and i make a click on the button, then the background does change a bit to make it looks like a button click, but it does not change back after the button have been click. Does somebody know what i mean and know how to let the button look again like before? At moment the button look just like before when i click him again.

 

Sleep(200);

then recreate the button or set the color back
